I tried following on my 8.0-CURRENT box:

----8<----8<----
abbe [~] monte-cristo% exec sh
$ echo "^$PKG-[0-9,._]+$"
^-[0-9,._]+$
$ uname -a
FreeBSD monte-cristo.france 8.0-CURRENT FreeBSD 8.0-CURRENT #21: Mon Nov 10 21:19:13 IST 2008     root at monte-cristo.france:/usr/obj/usr/src/sys/ULE  amd64
---->8---->8----

And as you can see in above paste, 'sh' doesn't evaluate $" as variable as 
it has evaluated $PKG as variable. this works with 'sh' shipped with 
8.0-CURRENT. Maybe some issue with your 'sh'.
