That's a snippet from a build log:

gcc -DHAVE_CONFIG_H -I. 
-I/var/tmp/portage/sci-mathematics/reduce-20110414/work/reduce-20110414/csl/cslbase 
  -Dfontsdir=reduce.fonts -I/usr/include/freetype2 
-DBINDIR=/usr/local/bin -DPKGDATADIR=/usr/local/share/reduce 
-march=core2 -mtune=generic -O2 -pipe -I/usr/include/freetype2 
-fno-strict-aliasing -O2 -Wall   -MT arith01.o -MD -MP -MF 
.deps/arith01.Tpo -c -o arith01.o 
/var/tmp/portage/sci-mathematics/reduce-20110414/work/reduce-20110414/csl/cslbase/arith01.c

I haven't looked at the code but I have strong feeling that precompiler 
directives:
  fontsdir
  BINDIR
  PKGDATADIR
may help you ;) It looks that removing 'local' is all you need. Then 
place everything which is not a binary and not a lib in usr/share/reduce

In principle you should always use /usr/$(get_libdir) from mutlilib.eclass.
