Issues building docs on an offline box again.

Hello all,

I'm having a strange issue build the man pages again on my offline box.

I have a copy of cygwin installed on both my online and offline box with the same configuration. On my online box, the man pages build fine. On my offline box I get the following dump:

$ make install-man
rm -f doc.dep+ doc.dep
/usr/bin/perl ./build-docdep.perl >doc.dep+
mv doc.dep+ doc.dep
make -C ../ GIT-VERSION-FILE

Settings/tvishe01/My Documents/git'

mv git-add.xml+ git-add.xml
rm -f git-add.1
xmlto -m callouts.xsl man git-add.xml

Strange thing is that I thought I had gotten these to build offline before with the exact same configuration. Any thoughts?

My current solution is to build them on the online box and then copy them over the sneaker net to the offline box. But, this is kludgey, so not cool. :)
