p5-XML-SAX-0.99 Install Error

If you’re trying to install p5-XML-SAX-0.99 and get a

Can't locate XML/SAX/Exception.pm in @INC

error then you may need to

cd /usr/ports/textproc/p5-XML-SAX-Base
make distclean
make deinstall
make install clean

Then you can

cd /usr/ports/textproc/p5-XML-SAX
make distclean
make install clean

And you should get an error free install. Apparently p5-XML-SAX-Base is a prereq that isn’t getting cleanly detected or updated in the make process for p5-XML-SAX.
