Trouble building haskeline on OpenBSD, due to libiconv?

[yary]

Hello,

I'm having trouble building haskeline. I suspect its my setup and not
haskeline, thus I'm not submitting a bug report in trac.

Here's the output from the build process:
pinky ~/pugs $ cabal install pugs

As you can see this is in the process of building pugs- I don't know
much about Haskell or cabal. If someone can tell me where to look I
can dig deeper.

Thanks!
