 > If you do, please note it here (including whatever fix that ends up
 being merged upstream). If you can attach a patchfile with your change and
 a portfile diff (which applies the patch only on 10.4), I'm likely to get
 to updating the port sooner than if I have to generate it myself (and try
 to test it somehow).

 I just came across this same bug. Type off_t is apparently not native to
 apple_gcc 4.2, but the code assumes it is. Changing
 {{{
 89  #if defined(LUA_USE_POSIX)      /* { */
     90
     91  #define l_fseek(f,o,w)          fseeko(f,o,w)
     92  #define l_ftell(f)              ftello(f)
     93  #define l_seeknum               off_t
 }}}
 in liolib.c to
 {{{
 89  #if defined(LUA_USE_POSIX)      /* { */
     90
     91  #define l_fseek(f,o,w)          fseeko(f,o,w)
     92  #define l_ftell(f)              ftello(f)
     93  #define l_seeknum               __darwin_off_t
 }}}
 works - that's the definition in /usr/include/sys/types.h - but that's not
 elegant nor 10.4 specific. I suppose you should check whether 'off_t' is
 declared at the top of the file (how? does ifndef work for types?) and if
 not, include sys/types.h . Where is this 'upstream' I should be reporting
 this to? I doubt I'll be able to write a Portfile, but I'm open to
 testing.
