>Description:

After gcc 4.5 update, I started rebuilding lots of packages. One of the
failures is print/cups:

I'm not sure how any of those would qualify as "a local symbol".

And one of the pkgs I rebuild was libtool-base (just in case it matters).

>How-To-Repeat:
On a completely current amd64 system, try to build cups from pkgsrc-current

n/a
