Failure in ghostscript-afpl upgrade

[Michael Dunham]

I think I may have read this was an ongoing problem, but I thought I 
would ask if anyone knows what the error I am getting in upgrading 
ghostscript-afpl is and if there is a fix for it.  I have noticed 
happening over a period of time with this port across several changes.  
I am using FreeBSD 5.1 Current and I did update the ports.

When I try an upgrade it stops with the following error shortly after 
finishing the drivers screen:
gmake:  *** No rule to make target 'obj/stp.dev', needed by 
'obj/gconfxx.h'. Stop.
***Error Code 2

Stop in /home/ports/print/ghostscript-afpl.
** Command failed [exit code 1]: /usr/bin/script -qa 
/tmp/portupgrade1692.0 make

** Fix the problem and try again
** The following packages were not installed or upgraded (*:skipped / 
!:failed)
              ! print/ghostscript-afpl 
(ghostscript-afpl-8.00_2)          (new compiler error)

Thanks

Mike
