problems with "make optional"

[Duke Normandin]

hey ...

New to Sather!

Compiler is working => sacomp

Compiling C for Browser...

I think that I have to nuke a file *before* trying to re-compile,
but I don't know (and can't find) which one.

tcl.h *is* on my system, but probably not in the usual spot because
I'm running Ubuntu 11.1 or something.

Any help / ideas would be appreciated!
