:-(

Have you attempted to see if there's anything the compiler can do to "fix"
the problem? I looked at the xlc docs and my usual source for shared liking
docs (http://www.fortran-2000.com/ArnaudRecipes/sharedlib.html) and here are
some things to try...

The xlc docs indicate there's an enabling runtime binding option, which is
what Linux-gcc does to enable the reverse binding you need. The option is
"-brtl".

The sharedlib.html doc says that one should specify "-bM:SRE" for creating a
shared library. No sure what it does, as I could not find docs on it.

And last, the xlc docs say that to create a "dynamic library" to use the
"-G" option. As we don't specify this, yet the *.so libraries seem to work
for you it seems a bit baffling how the current vacpp toolset works.

Other than that the only option left is for us to support using the <tag>
requirements in regular targets. I'll continue investigating how that might
affect other things.
