A colleague of mine had the same problem last week. I think the problem is
that IDL 5.5 has two versions for Solaris, a 32-bit version and a 64-bit
version. I think you are running the wrong version for the .so file you
have created. Try executing
> idl -32
to run the 32-bit version and see if that works.
