Yeah I can see --with-system-pgm was removed 2 years and a half ago, for 4.1.1 (when the embedded pgm source code was removed), by this PR: https://github.com/zeromq/zeromq4-1/pull/2 Should have been kept for compatibility, sorry about that. Changing to --with-pgm is indeed the right fix. -- Kind regards, Luca Boccassi
