There is an old patch to gnuplot that implements loading functions from
a shared library:
https://sourceforge.net/tracker/index.php?func=detail&aid=588805&group_id=2055&atid=302055
The patch is quite old, and probably would not apply to the current
source tree without modification. Nevertheless you might find it useful.
The chief concern raised at the time the patch was first proposed was that
it would not be portable to other operating systems.
I think we would be willing to consider a similar patch submitted against
the current cvs source, but still it would be desirable if the patch were
to support more than one operating system (linux, windows, OSX, SunOS, etc).
