Comment(by kcrisman):
I don't know if this is helpful, but when installing a new mpl spkg (which
jason knows about):
{{{
BUILDING MATPLOTLIB

}}}
and then, while doing the last extension (matplotlib._png)
{{{
ld: library not found for -lpng
collect2: ld returned 1 exit status
error: command 'g++' failed with exit status 1
Error building matplotlib package.
}}}
This is after installing this patch and #9210 patch. After moving Sage
and trying again, the same thing happened. After rolling back #9210 and
reverting it, same thing. After then moving Sage back to its original
location (which one of the last error message suggested might be causing a
problem, it was looking in a nonexistent local/lib at that point) the same
thing happened. After then reverting this patch as well... the same thing
happened. Just FYI.
And sage -f the standard mpl package went just fine, even though the same
info about pkg-config appeared. Not sure if this is relevant to this
ticket, but I hope it is!
