Errors install git-1.5.2.2 on 64-bit AIX

After I modified Makefile:

NO_OPENSSL=1 NO_CURL=1 NO_EXPAT=1

CFLAGS = -maix64 -g -O2 -Wall LDFLAGS = -b64 -lz AR = ar -X64

Make succeed:

bash-3.00# gnumake
GIT_VERSION = 1.5.2.2
    * new build flags or prefix
    CC convert-objects.o
...
    SUBDIR perl

-DETC_GITCONFIG='"/usr/git/etc/gitconfig"' -DNO_STRCASESTR
-DNO_STRLCPY -o test-genrandom -lz  test-genrandom.c

But install failed:

bash-3.00# gnumake install
    SUBDIR git-gui

    SUBDIR templates

gnumake: *** [install] Error 2

Thanks for some help.
