lapack @3.11: ld: duplicate LC_RPATH '/opt/local/lib/libgcc'

[krlong014 (Katharine Long)]

I got an error when building lapack port after clean installation.

After seeing the failure, I did the following:

sudo port -f uninstall installed
sudo port clean lapack
sudo port install lapack

Then all dependencies built correctly until the error:

Error: Failed to build lapack: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_math_lapack/lapack/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug.
Error: Processing of port lapack failed

I have attached the log file.

The error in the log is:

Zillions of other open tickets about that issue with various ports.
