building git on Solaris

Building git 1.7.1 on Solaris 9 using gcc and gnu tools.

My build environment includes:

    CC=gcc
    CFLAGS='-L/usr/local/lib -R/usr/local/lib'
    CPPFLAGS=-I/usr/local/include
    LDFLAGS='-L/usr/local/lib -R/usr/local/lib'
    LD_INCLUDE_PATH=/usr/include:/usr/local/include
    LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/usr/sfw/lib
    
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/ucb:/usr/ccs/bin
    PWD=/usr/local/src/git/git-1.7.1
    SHELL=/bin/ksh

If I ask `which make`, I get /usr/local/bin/make. If I say, `make --version`, I get "GNU Make 3.80".

If I ask `which perl`, I get /usr/local/bin/perl. If I say, `perl --version`, I get "This is perl, v5.8.6 built for sun4-solaris-thread-multi".

I'm building with

     # make configure
     # ./configure --prefix=/usr/local
     # make all doc
     # make install install-doc install-html

It seems to work fine (though way sparse in what it has to say), until it hits here (from the `make all doc`):

            :
            :
        GEN git-submodule
        GEN git-web--browse
        SUBDIR perl
    make: Warning: Ignoring DistributedMake -o option
    Usage : make [ -f makefile ][ -K statefile ]... [ -d ][ -dd ][ -D ][ 
-DD ]
                 [ -e ][ -i ][ -k ][ -n ][ -p ][ -P ][ -q ][ -r ][ -s ][ 
-S ][ -t ]
                 [ -u ][ -w ][ -V ][ target... ][ macro=value... ][ 
"macro +=value"... ]
    make: Fatal error: Unknown option `-C'
    make: *** [perl/perl.mak] Error 1

I couldn't figure out where that was coming from (Can I turn on a bit more verbosity during the build?) until I tried to do a `make clean` and got a little more detail, where it ended up with `make -C Documentation/ clean` followed by the same set of errors.

When I simply enter `make -C Documentation/ clean` from the command line, it works.

Poking around, I eventually found that /usr/ccs/bin/make will emit those errors, whereas /usr/local/bin/make does not. However, /usr/ccs/bin/make should never be called. That is last in my PATH, whereas /usr/local/bin/make is first in my PATH.

So, something fishy is going on with the environment. But, those path precedences are everywhere in my system. If I `su - nobody`, for example, I get /usr/local/bin first in the PATH. I also did a `find . -type f | xargs grep ccs` from within /usr/local/src/git/git-1.7.1, and the only things I found were in the config.log where it was noting /usr/ccs/bin/ar, /usr/ccs/bin/as and /usr/ccs/bin/ld, which, I believe, are correct.

Does anyone have any guidance or clues as to where I should look from here? Or how to fix this?

TIA

---------------------

NOTE: I also had to do the following:

    # diff configure configure.orig
    7810c7810
    <   for opt in -pthreads -lpthreads; do
    ---
    >   for opt in -pthread -lpthread; do
    #

to get rid of errors like this:

               :
               :
        CC xdiff/xpatience.o
        AR xdiff/lib.a

        CC imap-send.o

    gcc: unrecognized option `-pthread'
        CC shell.o
        LINK git-shell
   gcc: unrecognized option `-pthread'
        CC show-index.o
