[Mono-dev] Building source fails: gmcs command not found

I'm trying to build Mono from the git source under a brand-new installation of Fedora 18.

I'm following the instructions here:


When I run make, I'm getting a failure after a while while it's attempting to make the runtime folder:

if test -w /rootmono/mcs; then :; else chmod -R +w /root/mono/mcs; fi
cd /root/mono/mcs && make --no-print-director -s NO_DIR_CHECK=1 PROFILES=' net_2_0 net_3_5 net_4_0 net_4_5 ' CC='gcc' all-profiles
make[6] gmcs: Command not found

Now I'm pretty new to Mono - very, very new to trying to build it (first time) so I've got a steep learning curve to climb, but my reading of this:


 is that gmcs is the old compiler for 2.0 and mcs should be what's being used for newer stuff.

So I have a few questions.

First, and most obviously, is how do I get Mono to build in this environment.
Second, though, is I'd like to understand why this is failing.  Why is it trying to use gmcs in the first place?
