gmt6 @6.1.0 +gdal+nonfree+pcre is still broken after rebuilding it

[europasice]

Today I installed macports on my new macbook pro (Catalina 10.15.5). Xcode 11.5 Build version 11E608c

The base install of macports and all my usual ports installed fine except for GMT6. The screen said:

--->  Found 1 broken file, matching files to ports
Error: Port gmt6 is still broken after rebuilding it more than 3 times.
Error: Please run port -d -y rev-upgrade and use the output to report a bug.
Error: rev-upgrade failed: Port gmt6 still broken after rebuilding 3 times
Error: Follow https://guide.macports.org/#project.tickets to report a bug.

I've attached the output of port -d -y rev-upgrade to this ticket. I would appreciate any help you could offer for me to get GMT6 installed. Thanks.

There does seem to be something broken here.

Although gmt6 is installing proper libraries in /opt/local/lib, it is also installing improper libraries in /opt/local/bin—improper in that their install_name is set inside the build directory, a directory which of course doesn't exist anymore after the port has been installed, and improper in that libraries don't go in /opt/local/bin. This port builds using cmake, and it is normal for cmake to set the install_name incorrectly during the build and then to fix it up during the destroot phase. What's not normal is that it would install any libraries into /opt/local/bin.

Despite this situation, I believe the gmt6 port should be fully usable.

In e7f8a46920795a4aff4f359a3389fed1d15005c9/macports-ports (master):

gmt5, gmt6: install in ${prefix}/lib and create a symlink ${subport} to the gmt binary.

• remove broken libgmt.${version}.dylib and libpostscriptlight.${version}.dylib from ${prefix}/bin
