This assumes that the architecture has ldd, and the build is dynamic,
and the DLL extension is .so, and the names of required DLLs coincide
with names of libraries to link to; too many assumptions to make it
feasible...

This assumes that the library is not compressed.  On OS/2, the pages
of executables are compressed.

Nope; *the linker* can find it; but who said that *you* can?  If you
already know where the library file is, one can put pari.cfg alongside
it anyway for an easier solution...

Hope this helps,
