Forum OpenACS Development: Re: FYI: use tcl 8.6.4 for openacs
a) wait for a release / stable version and recommend tcl 8.5
b) add the (trivial patch) to the build process
c) use the head version of tdom.
So far, we sticked to (a). Variant (c) is no good policy, since this makes installs not reproducible, since tdom is potentially the "catch of the day". I'll bring up the question in the tdom forum...
