Thanks to Robert Bradshaw's tremendous help, we have the start of a
QEPCAD spkg for linux posted at
http://trac.sagemath.org/sage_trac/ticket/772
The spkg does not include source because we haven't sorted out licensing
issues. However, it does use wget to get the source from the webpage,
so you shouldn't have to do anything.
Currently the spkg compiles on my ubuntu 32-bit linux laptop (but has
linking issues; see the readline issue below). Apparently there are
some nontrivial issues with compiling SACLIB on OSX (dealing with the
FPU or something). It'd be great if someone who knew more about OSX
could take a look.
The spkg currently dies when trying to link to readline. Does anyone
know how to get a package to link to readline? The error is:
