Hi,

_envrion was not found, when linking libunix.a to a library on Mac OS X:

Undefined symbols for architecture x86_64:
  "_environ", referenced from:
      _unix_execvpe in libunix.a(execvp.o)
      _unix_environment in libunix.a(envir.o)

I added the following lines:

#ifdef __APPLE__ 
#include <crt_externs.h> 
#define environ (*_NSGetEnviron()) 
#else 
 extern char **environ; 
#endif 

to the flies:

otherlibs/unix/envir.c
otherlibs/unix/execvp.c

as they it was suggested here:

http://trac.macports.org/browser/trunk/dports/lang/hugs98/files/patch-packages-base-include-HsBase.h.diff?rev=81676

patches are attached to this email.

best,
Keyan
