This is actually a problem with finding/using the correct iconv library. See http://code.google.com/p/gpsee/issues/detail?id=19 for a (Haskell-related, even) discussion. I don't have SL so can't really help with this.
Thanks for the link. I don't see the Haskell connection - it's a JavaScript interpreter with its own FFI. But anyway... If this is the same problem, then I don't see how to proceed. In their case, it was two modules within their own project that were linking to the two different copies of iconv. They just needed to get the two modules to agree. But in our case, MacPorts readline is linking to MacPorts iconv as it should, and HP base is linking to native iconv as it should. So i've abandoned MacPorts readline, and I'm trying to build GNU readline manually. So far, I haven't been able to get this to work either. I have a number of questions: What version of GNU readline should I use? The current version is 6.1, but the Haskell readline package doesn't seem to support that. The highest version mentioned in HsReadlineConfig.h.in is 5.0. I tried 6.1 anyway, but unsurprisingly, Haskell readline didn't recognize it. What version should I use? Older versions of readline stubbornly refuse to build shared libraries on Snow Leopard. The make fails with: i686-apple-darwin10-gcc-4.2.1: -compatibility_version only allowed with -dynamiclib But I can't figure out how to pass the flag it wants. When I put it in CFLAGS or LDFLAGS, configure fails right at the start with configure: error: cannot run C compiled programs. Also - should I use -m32 or not when building readline? Could be that the real solution is to go back to Judah's GNUreadline.framework idea, and to arrange for the readline package to use it on the Mac. The only difference is that now the framework is not required for GHC as it was in the past, only for the readline package. It's clear that it is currently at least extremely difficult and non-intuitive, if not impossible, to use the readline package on Snow Leopard. That needs to be fixed. Thanks, Yitz
