About PLT Scheme v4.0
Have a look at Matthew Flatt’s thoughts about the pending release of PLT Scheme 4.0. He sets a definitive (if not authoritative) tone for what PLT Scheme v4.0 will, and will not, be.

PLT Scheme 3.99 (revision 10030) for the OLPC XO
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-3.99.0.25/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 the tarball and the md5sum for a trunk build that I made at revision 10030.
Here is how I did the build:
./configure --prefix=$WORKDIR/$DESTDIR --disable-gl --disable-shared --enable-origtree
make
make install
LeftParen
LeftParen is a framework for quickly creating web apps. It runs on PLT Scheme v3.99.0.23 or greater.
How to print a PLT Slideshow to a file
Here is how to print a PLT Slideshow to a file:
slideshow -P -c -o [output file] [input file]
- -P: print to postscript
- -c: (condense) flatten the output file in the case that you had built slides incrementally
Addendum: 05/17/08
The ‘ps’ argument doesn’t seem to work. I must have used the alternate ‘P’ originally for printing, but posted the other option, ‘ps’. As such, I’ve updated this post. I will look into this. Additionally I’ve changed the condense argument to ‘c’.
