bug in patching phase of cups-pstoraster

[Thierry Herbelot]

Hello,

I have here a R/O shared ports tree, under the /files2 mount point. A symbolic 
link points from /usr/ports to /files2/ports

On the machine, the temporary work dirs are hosted under /files4/tmp
(WRKDIRPREFIX=/files4/tmp in /etc/make.conf)

This usually works fine with all ports, except for cups-pstoraster after its 
recent change.

Here is the error log :

===>  Applying FreeBSD patches for cups-pstoraster-8.15
/bin/ln-sf /files4/tmp/files2/ports/print/cups-pstoraster/work/espgs-8.15rc3/pstoraster/gdevcups.c /files4/tmp/usr/ports/print/ghostscript-gnu/work/ghostscript/src
ln: /files4/tmp/usr/ports/print/ghostscript-gnu/work/ghostscript/src: No such 
file or directory
