Comment (by ccarey@…):

 Neither {{{_CS_DARWIN_USER_TEMP_DIR}}} nor {{{_CS_DARWIN_USER_CACHE_DIR}}}
 are defined in {{{<unistd.h>}}} in PPC Tiger. The simplest fix might be to
 change line 499 of {{{lib/support/PathV2.cpp}}} from

 {{{
 #ifdef __APPLE__
 }}}

 to

 {{{
 #if defined(__APPLE__) && defined(_CS_DARWIN_USER_TEMP_DIR) &&
 defined(_CS_DARWIN_USER_CACHE_DIR)
 }}}

 That change should allow PPC Tiger to use the non-Apple fallbacks in lines
 520 through 544.
