There were some recent security updates done to the XPM library and
most things that were compiled to use it.  This is across-the-board
with Solaris, Linux, BSD, Cygwin, etc.

What it looks like to me is that you're running a new version of the
XPM library, where they actually changed part of the API that we
used.  Xastir was updated to change how it called the XPM library to
generate the XPM file.  You probably need to update to the latest
CVS Xastir in order to have this work again.  Same thing for
printing as it uses similar calls.
