libgomp is already installed. It is listed in the line starting
with "Package versions:". There is states:
CXXLD is not showing its internals and the whole line linking the
library together is missing(?) in the log. Did you check, if it uses
-fopenmp at linker stage too? I wonder, because of this:
checking our pkgconfig cppflags... -fopenmp
checking our pkgconfig ldflags...
Do you see the same with your own pbuilder run?
If not, I would suggest to check config.log for issues with openmp.
Maybe some test went wrong and the linker flag wasn't added(?).
