Yes, and that supposition will result in problems for other users, not just me.

Yes, I can temporary disable it, but I see that will not solve the
issue for average user in the long run.

For example, if you checkout Ruby using Git (from official mirror)
then the revision parsing functionality on 1.9.2 will not work, as Git
will not be in the PATH.

I don't have tk or tcl in my system, so "--with-*Config" sounds
incorrectly, what should I provide to that option? empty value or a
path that doesn't exist just to avoid the issue?

Thank you.
