Here is my brute force method:
$ # extract the list of package defining custom pkg_preinst()
$ egrep -r "^.*?_pkg_preinst" /usr/portage/eclass/* |cut -f1 -d: |sed \
"s:/usr/portage/eclass/::g;s:.eclass::g" |sort|uniq| tee \
export-preinst.list
$ # extract the list of ebuilds inheriting gnome2 eclass
$ find /usr/portage/ -name "*.ebuild" -exec egrep -H "gnome2" {} \; | \
cut -f1 -d: |uniq| tee gnome-inherit.list
$ # wheeeeeeee
$ for x in $(cat gnome-inherit.list); do for y in \
$(cat export-preinst.list); do egrep --color -H "inherit.*${y}" $x; \
done; egrep --color -H "^pkg_preinst" $x; done | \
tee output-unformated.list
$ cat output-unformated.list |cut -f1 -d:|sort|uniq
of course YMMV and there might be simpler/faster solutions but oh
well... it gave me an output of 62 packages.
