PDL XS module linking problem

[Achim Gratz]

While trying to update PDL I've noticed a strange problem: some GSL XS
modules/DLL reference themselves and those modules that do cannot be
loaded anymore.  This does also affect my installed earlier version of
PDL which has worked before (I've kept the test logs), also when I
freshly compile this version.  Unfortunately, a lot of things have
been updated between the last time this was known to work and
now... does anybody have an idea what to look for or how to resolve
this?
