Which libraries does it check for that a standard system won't have?
I guess I'll find out.
On OS X my build fails with:
In file included from gen.h:39,

I guess this is Giac not finding GSL, NT, etc. Your autoconf
seems to have options to enable/disable GSL, NTL, etc., but I can't
tell wout to specify exactly *where* those libraries are installed
on the system (for Sage, they are in $SAGE_LOCAL).
On one Linux machine that I tried the buld *does* work, perhaps
because so much is installed system-wide on that machine.
The spkg I made is here:
http://sage.math.washington.edu/home/was/tmp/giac-0.7.4.spkg
this is really a tar bz2 file, so you can extract it with
tar jxvf giac-0.7.4.spkg
It took 31 minutes to build giac/xcas, and the build appears to work:

You're right, we definitely can't assume that latex2html is installed.
(Note: latex2html has a non-GPL-compatible license; we also
use it for the sage docs, since Python did, but I regret this dependency.)

Best is probably only running make install from the src subdirectory.
That's what I've done in the above spkg.

Very good.
Do you have any mirror sites of the complete giac/xcas webpage?
