If you have build binaries for other platforms, you might send them to me for inclusion in the binaries section. Other people using the same platform as you might be happy with this. Also if you have found (and solved?) any bugs or errors, I would be happy to hear about it.
The spec files used to build RPMs for Mandrake are in the tar files in the build directory. These may be useful (with some small adaptations) to build for other distributions.
Tcl8.3 and Tk8.3 should be installed first. The other packages are all dynamically loadable extensions. All these packages can be build using the following scheme (example for Extral):
tar xvzf Extral-2.0.0.src.tar.gz
./configure --helpeg. use --prefix for installation in /usr instead of in /usr/local. May depend on where your Tcl installation is
./configure --prefix=/usreg. use --disable-stubs for compiling with older Tcl versions (< 8.0.5)
