[Haskell-beginners] fail: wxhaskell with cabal

[Josh Bronson]

Hmm, there is no file of the type you mentioned:

$ ls /usr/lib/pkgconfig/wx*
ls: cannot access /usr/lib/pkgconfig/wx*: No such file or directory

A Google search for "wx pkg-config" appears to reveal that wxwidgets
does not support pkg-config, or at least it didn't a few years ago.
Lots of people will try "cabal install wx," right? So it seems like
that's probably not the problem, but I'm not sure where the code that
is generating the following output lives:

Configuring wxcore-0.12.1.2...
setup: Missing dependencies on foreign libraries:
* Missing C libraries: wx_baseu-2.8, wx_baseu_net-2.8, wx_baseu_xml-2.8

I tried untarring
~/.cabal/packages/hackage.haskell.org/wxcore/0.12.1.2/wxcore-0.12.1.2.tar.gz
and looking at Setup.hs to no avail. If I could see what test is
failing, I could probably figure it out.
