upgrading spamassasin to pkgsrc-2008Q4 problem with perl5.8 vs perl5.10

[Russell McManus <russell_mcmanus%yahoo.com@localhost>]

I upgraded a bunch of packages using pkgsrc-2008Q4, which brought perl
up to 5.10.  But this broke spamassassin.

I tried rebuilding and installing every perl package on my system, as
well as a clean rebuild of spamassassin.  But spamassassin kept looking
for modules from perl5.8:

I was able to run again after a recompile of spamassassin with the
following hack to Makefile:

I'm not sure what is the root cause of this problem, but I figured that
a note might be useful to others even without that.
