--- Comment #141 from Peter Dyballa <Peter_Dyballa at web dot de> --- There are two levels of optimisation left: remove MacPorts from PATH (+X11 and Perl, these two also removed from PKG_CONFIG_PATH). If anything then fails we'll need to investigate and fix. The second level of optimisation is MacPorts. After I had deactivated all ports there were left in /opt/local/bin hundreds of symlinks to software that was not there, for example Python 3.10 (which I removed at once). Most files probably belong to MacPorts' base (can be judged from time stamp, there is no other useful way left, except remove MacPorts completely, install the installer package and then build from sources again). So I am going to deactivate the nightly activated ports gmp, isl, libmpc, mpfr and gcc10-bootstrap, having nothing installed afterwards. Then I'll try to activate the symlinks port that can help me find dangling symlinks. Finally I'll possibly use 'port provides <path name>' thousands of times to check whether left files belong to some port – in theory they should not. Anyway, I'll create the biggest ticket MacPorts has ever seen – so to Trumple speak. Afterwards I should have a mostly clean MacPorts base installation.
