Comment(by drkirkby):
Should a C++ compiler be checked for too? Certainly rebuilding the Sage
library needs a C++ compiler, as running:
{{{
drkirkby@hawk:~/sage-4.7.alpha3$ ./sage -ba | grep g++
}}}
produces a lot of output. (You need to insert a "y", as the script asks
for that, though you can't see it because of the grep statement)
{{{

This is making me think we should perhaps check for a C++ compiler too,
but I'm not sure.
A basic install of an operating system might well have a C compiler, but
not a C++ compiler.
