What you were asking wasn't clear, and could have included a script
problem, a port update problem, a pkg_info problem, and/or a regex
problem. And then, I'm scratching my head wondering how you're making
use of the output of the -L switch.

If that's the case, where does your regex of "^$PKG-[0-9,._]+$" fit into
all this? And why would you expect pkg_info to match on something like
'^xorg-fonts$' when, AFAICT, there is no port by that name? Again,
you're not being clear.

The end-of-line anchors work fine. For the following I've used bash,
but you can copy the same into a /bin/sh script for identical results:
# pkg_info -Ex $PKG
# pkg_info -Ex $PKG.*1
# pkg_info -Ex ^$PKG.*1\$
I'd suggest you submit your script or an abbreviated version.
