I believe that weave is currently broken with gcc-3.2.3--something to do with a change in the definitions of C++ headers. I say this because a) while installing fine, weave's test suite conks out with massive errors, all gcc-related, b) The netcdf library has a similar problem compiling its C++ componets under gcc-3.2.3 and c) the netcdf developers say that it's a problem with changes to the C++ headers in gcc-3.2.3, and have fixed em. Not sure if this is the right place to report this, just thought you might want to know. Jordan
