Some success now. Reverting to building by hand, if I 1. edit config.ml to put "" quotes around the name of the GHC executable (since it contains spaces AND () ), 2. edit Makefile to add -package base-3.0.3.1 on to the --make line, things proceed through the build and install stage properly. For doing things by-hand, it would be nice if the 'configure' script automatically put "" quotes aroung the name of the GHC executable when generating config.mk. I took a look to see if I could figure out a patch to do that, but it wasn't obvious enough. Also, it would be nice if there were an lhs2tex version which worked out-of-the-box with base>=4, since hacking the Makefile for that seems, er, sub-optimal? Best would be if cabal was cygwin-friendlier. Unfortunately, that seems to be a lot easier said that done :-(. Now I have to see if 'poly' style *actually* works... Jacques
