Nah, this is Usenet (from my POV).  Or Google Groups.  Or possibly a
mailing list.  In any case, casting aspersions is often done with
without regard to or even possesion of the facts.  :)

Yep.

I think even "make install" should have worked -- since it will
install in /usr/local, right?

All that should be involved is installing the "-devel" versions of a
few libraries -- exactly which ones depend on what features of Python
and the standard libarary you care about.  A few minutes with Google
would have ironed out any questions in that regard.

Doesn't 'make install' still install in /usr/local?  (I haven't
manually built built from sources for some time.)  If that's the case,
it shouldn't interfear with the installation in /usr.

But, you're right: anybody who spent more than a half hour on this is
either a flaming incompetent or a scam artist.
