I just spent a very frustrating hour trying to get the functional MetaPost library (a Haskell DSL for generating MetaPost) working. It installs (via cabal-install) without a hitch, but I haven’t been able to get it to actually work. I can write a test program which imports the FMP module, and compile it, but then when I try to run it, it spews out a gazillion .log, .tmp, .mpx, .aux… files and a nasty-looking series of error messages (including a segfault). I’m happy to provide more details if anyone thinks they would actually be able to help…

All the more motivation to get back to a rewrite of my diagrams library…
