[GRASSLIST:56] GRASS 5.0.2 on Mac OSX and libdl.1.dylib - solved

[Nick Cahill]

Installing the latest version of dlcompat (available at 
http://www.opendarwin.org/projects/dlcompat/) fixed this. You need to 
have the (free) developer's tools from Apple installed. Dlcompat is a 
tiny download; the developer's tools is a huge download (300 meg or 
something). If anyone would like I can email them the libdl.1.dylib 
file; just putting that in /usr/local/lib might work, although I can't 
test this myself.

For what it's worth, GRASS 5.0.2 running under Apple's X11 is *much* 
faster than 5.0.0 under the older version of XDarwin. It's probably the 
hardware acceleration in Apple X11; the difference is striking.
