I've tried to use this interface.
I have a recently-installed REDUCE-3.8 and TeXmacs- on Gentoo 

This is what I've done:
1. Corrected my .reducerc as suggested in README
2. Copied bin/tm_reduce to /usr/libexec/TeXmacs/bin/
3. Copied the whole tree to /usr/share/TeXmacs/plugins/reduce
4. Corrected weird permission bits (in reduce.tar.gz, permission bits seem 
to be copied from /dev/random :-)
This is what I have:
1. There is no "Reduce" in the menu under the icon which looks like a 
computer. I have reduce in my path, and it works.
2. If I choose "Other", Session type "reduce", session name "default", I 
get the following message at the bottom of the window:
plug-in 'reduce' not declared

What am I doing wrong?

Another thing that bothers me. In the directory install of the plugin, 
there is a long file tmprint.red. It is, clearly, a copyrighted material, 
and not under the GNU GPL license (or am I wrong?) It does not seem 
appropriate to distribute it in the GNU TeXmacs tarball. All files in it 
are free software, and most are covered by GPL (Joris, am I right?)
This is exactly the reason why I distributed only patches against 
fmprint.red: of course, these context diffs contained some files from the 
proprietary program fmprint.red, but I hoped that this is not a big 
violation. Those few lines could not be used for anything, except for 
applying the patch by a legal user of REDUCE. Now we have a complete file 
tmprint.red. Do we have permission of all copyright owners (A.C.Hearn 
etc.) to distribute it?

I hope these problems will be solved, and the new, better REDUCE interface 
will be distributed with forthcoming versions of TeXmacs.
