Sorry David, still no joy.

I updated to
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.2.1

and
$ rpm -q wxhaskell-gtk2.4.2-ghc6.2.1
wxhaskell-gtk2.4.2-ghc6.2.1-0.7-0

downloaded today from sourceforge.

$ make distclean
<snip>
$ ./configure --with-wx
<snip>
$ make
<snip>
ghc  -cpp  -package unix -package text -O -funbox-strict-fields -package wx
- -DHAVEWX -package wx -Wall -DHAVE_CURSES -package util -fffi -c
SelectChanges.lhs

SelectChanges.lhs:89:
    Cannot unify the type-signature variable `a' with the type `()'
        Expected type: IO a
        Inferred type: IO ()
    In the expression:
        start
        $ (do
             parent <- frame [text := cap_jn]


(I assume the change in reported line number is due to the upgraded ghc).
