DrScheme is very, very close to its 4.0 release. I wanted to try out the newest bits on my OLPC XO using one of the nightly builds, but ran into the same problem as I did last time:
/home/olpc/apps/plt-126.96.36.199/bin/mred: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory
Some folks have resolved this dependency using Mesa for OpenGL emulation, but I found it easier to prepare a build that doesn’t depend OpenGL.
Here is how I did the build:
./configure --prefix=$WORKDIR/$DESTDIR --disable-gl --disable-shared --enable-origtree
