making the src.rpms generally.

I found that several src.rpms making fails with the same output:
...
checking for dlfcn.h... yes
checking for i686-redhat-linux-gnu-g++... no
checking for i686-redhat-linux-gnu-c++... no
checking for i686-redhat-linux-gnu-gpp... no

See `config.log' for more details.
error: Bad exit status from /var/tmp/rpm-tmp.70505 (%build)
Something common, source packages independent should be here. What can
this be?
