[tlbuild] Building on the Macintosh (Part 2)

[Richard Koch]

Karl,

This causes an earlier error when compiling poplar:


depbase=`echo poppler-src/goo/gfile.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\

Could you add Akira Kakuto's patch to XeTeX to the sources, at least temporarily, so I can test it. Here's
the patch:


Norbert says that I must run reautoconf after changing via this diff, but there is no such program on El Capitan, and I'm not very game to changing the compile system if I don't have to.
