The starting point for getting help is the LSB Project Web site, www.linuxbase.org. One of the subprojects is the LSB Build Environment, whose link takes you to the page containing the latest information for the build environment.
A mailing list, lsb-build@freestandards.org, is available for discussion of build environment issues at freestandards.org/mailman/listinfo/lsb-build.
In addition, you usually can catch some of us on IRC at irc.freestandards.org/#lsb.
