/usr/bin/pod2man and /usr/bin/pod2html are not executable on my machine. to get the package installed I ...

1. mv /usr/bin/pod2man /usr/bin/pod2man.bak
2. ln -snf /usr/bin/pod2man5.8.9 /usr/bin/pod2man
3. mv /usr/bin/pod2html /usr/bin/pod2html.bak
4. ln -snf /usr/bin/pod2html5.8.9 /usr/bin/pod2html

reran port install and it works.

Upon investigating, this pod2man and pod2html work well with the perl from macports, but don't work well with the perl 5.10.0 / 5.8.9 hybrid installed on snow leopard. The pod2man, pod2html files indicate that the perl interpreter is supposed to differentiate between the versions. When libcerf builds it's man pages, it calls both programs without specifying a version, eg. /usr/bin/pod2html rather than /usr/bin/pod2html5.10.0 and fails to build because pod2html and pod2man are not executable. (Whereas pod2man5.10.0, pod2man5.8.9, pod2html5.10.0 and pod2html5.8.9 are executable.) I have attached a patch that should be applied only to snow leopard installs without a macports perl installed. It hardcodes pod2{html,man}5.10.0 instead of pod2{html,man}. I do not know of a way to have macports apply a patch to only snowleopard, however, this task is still to be done. Perhaps a better fix would be to predepend on a macports perl version?
