bulk88's comment at [1] ("A wild guess is you have -DDEBUGGING on the
cmd line to the CC in your module. DEBUGGING can only be set at perl
interp build time, not randomly, per module, afterwards.") sounds like
there is an expectation that turning on debugging shouldn't break
the handshaking? If so, perhaps there is a bug here that could be
addressed upstream - which would obviously be good news for any
binary distribution.
