In the beginning was equery 0.1.4, written by Karl Trygve Kalleberg,
which searched the portage tree for matching package names:
Code:

equery list man-page
   * installed packages
  sys-apps/man-pages-3.23
  sys-apps/man-pages-posix-2003a

Then it was improved to the current equery 0.3.07, with explicit wild-cards:
Code:

equery list \*man-page\*
  !!! Invalid CPV: '*man-page*'

There were problems with the pattern matching, which couldn't handle
entries with '-', but there's a patch for that somewhere in the archives
and I finally got annoyed enough by inadmissable searches to add it:
Code:

equery list \*man-page\*
  sys-apps/man-pages-3.44
  sys-apps/man-pages-posix-2003a

Then equery started detecting invalid package names; a really good idea,
except that one way of temporarily keeping local overlay entries out of
the way of emerge is, you've guessed it, renaming them:
Code:

equery list -p \*man-page\*
  Invalid ebuild name: /usr/local/portage/sys-devel/gcc.org/gcc-4.4.5.ebuild

  Invalid ebuild name: /usr/local/portage/sys-devel/gcc.org/gcc-4.5.3-r2.ebuild

  app-i18n/man-pages-da-0.1.2
  app-i18n/man-pages-de-0.8
  app-i18n/man-pages-de-0.12
  app-i18n/man-pages-fr-2.39.0
  app-i18n/man-pages-it-2.65
  app-i18n/man-pages-it-2.80
  app-i18n/man-pages-ja-20070515
  app-i18n/man-pages-ja-20101110
  ... etc

But being intelligent as well as beautiful I soon found a way around the problem:
Code:

equery list -p \*man-page\* 2>/dev/null
  sys-apps/man-pages-3.28
  sys-apps/man-pages-3.29
  sys-apps/man-pages-3.30
  sys-apps/man-pages-3.31
  sys-apps/man-pages-3.32
   ... etc

So finally, after a lot of work by skilled developers, we have an equery
that is only slightly more inconvenient than the original.

Excuse me, but I'm off to write a quick and simple Portage tree scanner...

Have you looked at app-portage/portage-utils?

To put things into perspective, half of those "problems" were caused by changes in portage, not equery.

They could also use something like porthole, that is if it being run from within X.
