Thanks for that. I also considered cobbling a script to reconcile
things, but in the end, felt simply un-installing Perl and the
some 200 modules would be both faster, and less prone to failure.

I ran into problems in my first attempt to use portmaster(8), issuing
portmaster -a. It failed on a number of ports, and I was forced to run
it several times. I had some difficulty with it given that not all the
options are quite clear -- "-s", for example. One can only infer it's
action(s) from the context it used within the man(1) page, it doesn't
literally explain it's intent.
In the end, I was forced to perform many "make reinstall" jobs, which
left the dependency records _way_ out-of-whack -- pkg_info:
pkg_info: corrupted record (pkgdep line without argument), ignoring.
Forcing me to resolve the issue by cobbling && running the following:
grep "^@pkgdep" /var/db/pkg/*/+CONTENTS | awk '{ if (NF != 2) { print $1 } }' | cut -d':' -f1
I redirected the output to a file, where I then "cat | sort -u" to
another file, which left me with a list of the ports to reconcile.
performing a "portmaster --check-depends" resolved the problem.
I guess the only _sure-fire_ way to resolve my issue, is to catalog
all of my installed Perl modules, and remove Perl 5.12, and the
modules. re-install Perl 5.12.5, and cobble a script to install all the
modules I currently have installed.
My perl5 tree currently looks like:
/usr/local/lib/perl5/5.12/man/
man3/
whatis
/usr/local/lib/perl5/5.12.4/
man3/
whatis
What a mess!
In the end, I guess the moral of the story is; don't upgrade.
I've been on BSD since the late 70's, and as such, am no stranger
to the upgrade path. But recent experience seems to show, things
aren't getting any easier (or necessarily better). :(

I don't think I'm even willing to go there, after this mess.
Thanks again, for taking the time to respond.
