[Slackbuilds-users] matplotlib does not build on 1 of 3 systems

[Larry Hajali]

Looks like your PyQt package is not compatible with the installed sip
package.  I get similar errors on calibre 1.x versions because I upgraded
sip to a newer version for building PyQt5.  You might want to reinstall
PyQt and sip on the system that is giving you problems.
