Missing build depency for security/gnome-keyring

[Uwe Klaus <uklaus%hgb-leipzig.de@localhost>]

Hi,

it seems that security/gnome-keyring needs textproc/py-expat for building.

Without installing textproc/py-expat I get the following error.
gmake[4]: Entering directory 
`/tmp/pkgsrc/security/gnome-keyring/work.hgb2/gnome-keyring-2.26.0/gcr'
