Hi,
building ghc-6.10.3 under x86 solaris eventually failed with: [...] Configuring haskeline-0.6.1.5...

I wonder how this check for -liconv is generated. I have a file /usr/include/iconv.h but not file /usr/lib/libiconv.*
Under Linux I've installed successfully http://www.haskell.org/ghc/dist/6.10.3/ghc-6.10.3-i386-unknown-linux-n.tar.b... and I was able to install http://hackage.haskell.org/packages/archive/haskeline/0.6.1.6/haskeline-0.6.... without libiconv!
./Setup configure Configuring haskeline-0.6.1.6... checking whether to use -liconv... not needed.
However, the mere existence of /usr/local/lib/libiconv* files causes configure to use -liconv:
checking whether to use -liconv... using -liconv.
The actual cause is an evil /usr/local/include/iconv.h file that is found first and cannot be easily excluded. But passing the option "-isystem /usr/include" to gcc or setting export C_INCLUDE_PATH=/usr/include makes the haskeline installation not use "-liconv". Cheers Christian
