Yes the config.log does say that, but are you sure that's a problem?

This is part of the configure script's check for which lex library to use. As a result of the undefined _yywrap symbol error you pointed out, it determined that it should use the l lex library:

checking lex library... -ll

And the configure script proceeded. So this error in the config.log does not necessarily indicate a problem.

configuration does eventually fail, for me (and presumably for you, though you did not attach the main.log which would have told us for sure) due to the message:

configure: error: gdlib-config not found in /opt/local (tried /opt/local/bin/gdlib-config)

That's already tracked in #64342.

This might already be fixed in a newer version of mapserver. That's already tracked in #49485.

A pull request was submitted 8 hours ago to address both issues and will hopefully be fixed and merged soon.

thx, and I'll try again with new version mapserver 8.0.1

mapserver was just updated to 8.0.1, and should be available within another hour or two. Let us know if it fixes the issues!
