I figured this out for myself. "man -k alternatives" pointed to "update-alternatives" whose man page showed me the official way to deal with this situation. update-alternatives --display tclsh showed the (8.4 and 8.5) possibilities, and update-alternatives --config tclsh allowed me the choice of symlinking tclsh to tchsh8.5. As a result HAVE_TCL_GT_84 is automatically set correctly to 1 (True) for our CMake build system on my platform. Once again, Debian has come through for me. Alan __________________________ Alan W.
