[QGIS-Developer] QGIS 3.8.0 on FreeBSD: build takes several hours

[Rainer Hurling]

As the maintainer of the QGIS port for FreeBSD, I am preparing a port
for the recent update to QGIS 3.8.0.

The build process takes a very long pause of several hours(!) at about
21% of the code, before it proceeds:

This seems to happen since #18fb3f2 [1] (committed 2019-05-13, submitted
2019-04-30). Before the commit, the build process takes a normal
duration on FreeBSD.

As far as I can say, the problem occurs with both proj-5.1.0 and
proj-6.1.0. GDAL version is 2.4.1, the OS is FreeBSD 13-0 CURRENT amd64.

Does anyone else observes something like this? I suspect, that the long
pause has do with a conversion problem into the proj db. What do you think?

Thanks for any help. And please let me know, if I should provide more
information or test something.

Best wishes,
Rainer Hurling
