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

[Jim Diamond]

Hi,

I'm trying to compile matplotlib on some Slackware64 14.1 systems, all
with multilib.

On 2 of the 3, it compiles fine using sboinstall and/or sboupgrade.

On the third, my attempts are rewarded with the following:

I've compared the packages installed (and their versions) on all three
systems, and while there are a few differences, I didn't see any
difference which looked like it should affect any of Python, PyQt or
Qt.  (Admittedly, I may have missed some significant difference.)


Does anyone have any insight as to what I might be looking for?
Obviously I can copy over the package from one of the successful
systems and install it (whether it would work correctly is another
issue), but I'd rather have some idea about what the real problem is.

Thanks.
