G: One thing which might make a difference: try adding "-lpthread" to
G: the link command. I've occasionally encountered all sorts of odd
G: behaviour with programs which are linked against libraries which are
G: linked against libpthread (typically libGL), but where the binary
G: itself isn't linked directly against libpthread.

That works(!)

although I guess it really belongs somewhere else in the build system..?
or is it a bug in the debian build of the tcl8.4 libraries? (as 8.3 works ok)



thanks again,
