Comment (by vbraun):
If `kbmag` only uses stdin/out to communicate with its binary component
then it should work. The `Exec` GAP function basically works when calling
it via libGAP
{{{
sage: libgap_exec = libgap.eval("Exec")
sage: libgap_exec
<Gap function "Exec">
sage: libgap_exec('echo $HOME')
/home/vbraun

There is a segfault when returning the result, I'll fix that in another
ticket (maybe #13588).
How did you install `kbmag`, I don't think its one that we ship. Is there
a spkg for it?
