 Despite I have set everywhere to use macports-gcc-7 and explicitly
 blacklisted later versions of gcc in port file of JAGS, it still asks to
 download GCC11 - which is known to fail to build on PowerPC Macs.

 It is not listed in dependencies in port file, so I am out of options how
 to force it use gcc7 instead. Any ideas?
