The unfortunate problem with OSX is that there are several Unix package systems -- brew and fink and possibly others.  And they are different.  And they keep stuff isolated from OSX so you end up with duplicate copies of stuff.

It is perfectly straightforward to do a standard install on various packages, which lands them in the GNU standard prefix /usr/local.  So for those of us who prefer to do it that way rather than mess with unhelpful tools, it would be nice if SIMH would understand this.
