That should _not_ be the case, since gcc6-aux should not make use of it and gcc6-aux is not configured to download isl and use it during build time.

If you could provide more details about your system that would be nice. Specially if you include the initial configuration of gcc6-aux, which should give information about if it is pulling isl into the build or not.

I can build dejagnu directly when I go to devel/dejagnu and 'make install'. But it pulls lang/gcc10 instead of using gcc10-aux. Once again, I am pretty sure that is due to the way pkgsrc infra is set up.

But then the build of wip/gcc10-aux fails with:

...
