>Description:
xpm is included in Solaris 9, and the pkgsrc xpm package detects this. 
Dependent packages fail to buildlink however.
>How-To-Repeat:
Build a package that depends on xpm, such as emacs.

===> Required package xpm>=3.4knb2: NOT found
===> Verifying package for ../../graphics/xpm
===> xpm is part of your X11 distribution
===> Returning to build of emacs-21.4a
...
===> Creating toolchain wrappers for emacs-21.4a
xpm is not installed; can't buildlink files.
>Fix:
Force the pkgsrc xpm package to be built. Comment out 

#.if !empty(IS_BUILTIN.xpm:M[yY][eE][sS])
#PKG_SKIP_REASON= "${PKGBASE} is part of your X11 distribution"
#.endif

to ignore the builtin detection.


In order to build xpm with gcc on Solaris, the following lines in 
/usr/local/lib/X11/config/site.def must be uncommented:

#ifndef HasGcc2
#define HasGcc2 YES
#endif

#ifndef HasCplusplus
#define HasCplusplus YES
#endif

It would be nice if this was documented somewhere (I stumbled upon it), or if 
somehow pkgsrc enabled these imake defs automatically when using gcc (I have no 
idea how).
