When you install Xcode 2.5 or 3.0, one of the installation options is
to install the "Unix command line tools" or something like that. This
puts copies of all the tools that were in /Developer/usr/bin into /usr/
bin so that you can use ordinary Makefiles. You can make most
Makefile projects work just by changing your path to include /
Developer/usr/bin but some really bad Makefiles actually call out /usr/
bin/gcc explicitly! IIRC, it is on by default, so maybe Larry
unchecked it.

Well, that's a little weird...
There's a couple followups about gdb in /Developer/usr/bin, but I
have an additional copy in regular /usr/bin:
$ ls -l /usr/bin/gdb /usr/libexec/gdb/gdb-i386-apple-darwin /
Developer/usr/bin/gdb /Developer/usr/libexec/gdb/gdb-i386-apple-darwin
-rwxr-xr-x 1 root wheel 4867 Oct 2 00:19 /Developer/usr/bin/
gdb
-rwxr-sr-x 1 root procmod 6073712 Oct 2 00:19 /Developer/usr/
libexec/gdb/gdb-i386-apple-darwin
-rwxr-xr-x 1 root wheel 4867 Oct 2 00:19 /usr/bin/gdb
-rwxr-sr-x 1 root procmod 6073712 Oct 2 00:19 /usr/libexec/gdb/
gdb-i386-apple-darwin
I'm guessing this is also the case for Jim Ingham who suggested the
command... so it might be a good question why it's not true for
Laurence... might be a broken install? /usr got deleted on his
system or something? Or do I (we) have an extra unintentional copy
in /usr that's going to be ignored by future updates and eventually
go out of date and bite me later? :)
Also, I was going to say 'sudo' isn't necessary, but apparently it
is in the specific case of attaching gdb to gdb. Cute trick, I
would've seen the error it gives without 'sudo' and just thought
it's something that can't be done. (that would suck for the gdb
developers! ;)
