Comment(by mister.wardrop):
@leif: Thank you for your helpful tips. I was aware that I could put the
build into parallel mode; but had read somewhere that this was
experimental and may cause problems. I did it anyway; and atlas is now
built. But now, on all of my machines, it bails out when trying to compile
singular. Before I post another bug, can you verify I am not doing
something silly?
The error is: {{{ *’ [-Wwrite-strings] ../kernel/libkernel.a(mod_raw.o):
In function `dynl_open':
/Storage/Tools/sage-4.7/spkg/build/singular-3-1-1-4.p9/src/kernel/mod_raw.cc:217:

I think it would be solved by adding -ldl to the end of the compiler
command; I'm just not sure where to do that in the Sage automated install.
Any ideas?
