extract of main log (full log 16 MB and can't be uploaded)

[ryandesign (Ryan Carsten Schmidt)]

Usually you should upload the full log, compressed if it is large, but it looks like you've found the relevant part of the log, and I am able to reproduce the problem, so that should be sufficient.

This may be more fallout from type changes in the FT_Outline struct in freetype 2.13.3; see for example #70831 where this affected another port.

The last release of dia was in 2014. Upstream development continues but they are apparently in no rush to create a new release.

Unfortunately we'll have to come up for the fix for this ourselves, or see if another distribution has one, because upstream ​deleted the diapsft2renderer.c file that the error occurs in five years ago and ​deleted the postscript plugin entirely two years ago.

I see Gentoo has ​a bug report about and ​a fix for this problem.

[captainproton1971 (Captain Proton)]

Thanks so much for the feedback, I'll compress the log file next time.

As for the fix, I can look into implementing the Gentoo team's fixes in the macports portfile, but it won't be before the weekend. Also, I've never submitted a portfile patch before, so I'll probably need some time to figure out how to do so.

Cheers, Michael

[ryandesign (Ryan Carsten Schmidt)]

I can probably do it if reminded often enough.
