First, the downloaded file giac-0.9.2.tar.gz does not correspond to the Manifest. After regenerating the Manifest, it fails to compile:

libtool: compile:  i686-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I.. -DIN_GIAC -I. -I.. -I. -I.. -O2 -march=native -pipe -fno-strict-aliasing -DGIAC_GENERIC_CONSTANTS -c ti89.cc  -fPIC -DPIC -o .libs/ti89.o

The downloaded giac-1.0.0.tar.gz has size which differs from the Manifest. After re-generating Manifest, it compiles, and command-line version works. However, I specified USE=fltk, but giac was not configured to build xcas, the fltk front-end to giac. It installs a stub xcas; when started, it just says

No GUI support, try cas instead or recompile Giac with
./configure --enable-fltk-support
make clean ; make

Inspection of configure shows that this option is, in fact, called --enable-gui; however, configure fails to find the installed fltk-1.3.0-r1. Some patching of configure.in is needed. Also, there are other interesting configure options: --enable-lapack, --enable-pari, --enable-gsl, --enable-gc, maybe, something else. They should be controlled by USE flags and have corresponding DEPENDs.

I'm pretty sure this is fixed, and moreover sci-mathematics/giac-1.7.0.1 is now in the main tree. Please give it a try and report any problems you find.
