Bug#1082679: freedoom: FTBFS with .dsc from archive: mis-detects that deutex does not support PNG

[Santiago Vila]

Thanks for the testing. Some more data to consider:

- When I build with 1 CPU, I have never found the build problem so far.
- When I build with 2 CPUs, I got a failure rate of 66%
(16 failures over 24 tries so far).
- Given that 66% > 50%, "does not build from source" is more
true than "builds from source" (so please do not downgrade).

Given the above, my suspect is that this could be a Makefile bug,
and that it will not fix itself by merely doing another upload.

I would try how it behaves when using --no-parallel.

Thanks.
