Sigh. Yeah, I just looked past the answers.

The 1.2.8 and 1.2.10 is immaterial. What matters is what versions of
the unix libraries you had when you built the gtk/glib port. FreeBSD
put getresuid in libc_r, which applix isn't loading. So if your
FreeBSD has getresuid, the port config will find that version, try and
use it - and fail for applix. If the system doesn't have it, the port
config builds it's own in, and that works fine.
The solution I use is to compile this little C function. It returns a
failure, which causes gtk/glib to do the same thing it does if
getresuid isn't there. Others prefer C++ so they can drop the
paramenter names, but that makes the object slightly larger.
/*
* Fail a getresuid call so that clients will use it properly.
*
* compile as cc -shared -fPIC -DPIC -o getresuid.so getresuid.c
*/
#include <sys/types.h>
int getresuid(uid_t *a, uid_t *b, uid_t *c) {
return 1 ;
}
Next install the resulting getresuid.so somewhere reasonable - like
/usr/local/lib. Then change the applix shell script to define the
environment variable LD_PRELOAD to be the name of the .so file before
it starts the applix binary.
