[Xotcl] troubleshooting

[Jeff Hobbs]

The ActiveTcl release is straight from Tcl head of Oct 4 (just after IPv6 went in).  The b4 designate just means we've had 4 releases since the first beta, the core version is what the core responds as.

Note that one major change with AT 8.6b4 is that it's x86-x64, not x86-ppc (aka "universal"), so you need the right matching libraries.
