It's not enough to try to link against libiconv and look for a symbol iconv_open, because iconv may be installed in a way that internally renames iconv_foo to libiconv_foo in the library and adds corresponding #define iconv_foo libiconv_foo to iconv.h.

This patch is needed on OpenBSD (but it's not enough, since cabal suffers from the same problem).

Thanks for the patch; unfortunately, it makes the build fail for me on OS X: Undefined symbols: "_iconv_close", referenced from: _s20j_info in libHSbase-4.1.0.0.a(Iconv.o) "_iconv", referenced from: _s218_info in libHSbase-4.1.0.0.a(Iconv.o) "_iconv_open", referenced from: _s20d_info in libHSbase-4.1.0.0.a(Iconv.o) ld: symbol(s) not found collect2: ld returned 1 exit status make[1]: *** [utils/hsc2hs/dist-install/build/tmp/hsc2hs] Error 1 make[1]: *** Waiting for unfinished jobs....
