Yes: current Xcode, nothing else.

Good to know. I removed those options and tried again.

Thanks for that suggestion. I'm now using this (with 9.6.3):

./configure PERL=/opt/bb/170704/bin/perl --with-perl --prefix=/opt/bb/170704

I still get the error. I don't see how Perl can make the difference,
but I guess it's not relevant that I can't see it ;-(

Thanks for taking the time to answer.
