MacPorts is calling in libomp and clang on PPC, which of course are not (presently at least) available. So you may see tickets, which is the only reason I mention this.

Can you give specific examples, preferably with logs? On ppc,
macports-gcc compilers are preferred over macports-clang:
<https://github.com/macports/macports-base/blob/v2.6.1/src/port1.0/portconfigure.tcl#L1097>

So I don't immediately see how what you describe could happen, unless
the ports are also blacklisting *gcc* or something.
