So...
Rev 24206, on an intel mac OS X 10.5.6, the Makefile doesn't seem to be generated properly wrt gettext, this problem has only appeared for me in the last few days.
Here the applicable output from the config script.
checking libintl.h usability... yes
checking libintl.h presence... yes
checking for libintl.h... yes
checking for library containing gettext... -lintl
This looks good, but here's how the Makefile looks:
CLIENT_LIBS= -lz -lcurl -lssl -lcrypto -lz -ljpeg -logg -lvorbis -ltheora -ltheora -lpng -ltheora
If I add -lintl myself there are no problems, but I'm wondering why it's not generating the Makefile properly, it did identify -lintl as a library of interest after all. And yes the theora lib is doubled + tripled, it's not a typo.
