There's a table (wired in) to cabal2arch, that gives the necessary
translations between C libraries that appear in Cabal files (e.g.
"pangocairo") and the actual C library name on Arch (e.g. "pango").

This list should be an external, shared file (its not currently). The
main job of the cabal2arch maintainer is to keep adding translations to
this list.
