Not many, I dont know anything about shared libs on Solaris myself.
You might want to try some minimal tests like

    guile> (define d (dynamic-link "libX11.so"))
    guile> d
    #<dynamic-object "libX11.so">
    guile> (dynamic-func "XOpenDisplay" d)

Wait I just noticed something...

    guile> (define d (dynamic-link "libgtk.so"))
    ERROR: In procedure dynamic-link in expression (dynamic-link "libgtk.so"):
    ERROR: ld.so.1: guile: fatal: relocation error: symbol not found: g_strcasecmp: referenced in /homes/vollmer/lib/libgtk.so
    ABORT: (misc-error)

    Type "(backtrace)" to get more information.

This is analogous to your problem, right?

I can only speculate here that libgtk.so needs libglib.so but does not
contain enough information to have the dynloader load it
automatically.  This might be an instance of the interlibrary
dependency stuff that libtool has some problems with.

But libguilegtk.so loads fine:

    guile> (define d (dynamic-link "libguilegtk.so"))
    guile> d
    #<dynamic-object "libguilegtk.so">

It looks like as if libguilegtk.so contains enough information about
its dependencies on other libraries.

Yes, it is likely that in later versions libguilegtk.so is build
differently, so as to include this extra information on library
dependencies.
