This package is a QA nightmare :-( It bundles modified sources of 
x11-libs/fox (it does not compile with the system fox). First, it compiles 
this bundled fox, and installs it somewhere inside the build tree. Then it 
configures csl (and thus finds this freshly installed fox) and compiles 
it. Then it compiles reduce with csl. During this process, autoconf is 
called from make ("maintainer mode") many times. And each time, the 
arguments of the top-level configure are passed to all configure scripts 
in subdirectories. --with-gui is needed by one configure script (this is 
controlled by the USE flag X; with -X, fox is not built, and csl and 
reduce work at the command line only). But this --with-gui is passed to 
all configure scripts in various directories (fox sources, for example), 
and these scripts don't recognize this option. Ugly, but this works.

Many thanks. Looks OK.

I really want reduce to become more popular. There are only 3 free 
computer algebra systems: maxima, reduce, axiom (I don't count toys like 
yacas; and axiom has forked into axiom, openaxiom, and fricas). reduce is 
mature (from late 60s), powerful and very efficient. So, I have to live 
somehow with the weirdness of its current build system.

I suppose I can keyword it ~amd64, so that more users will have a chance 
to install it.
