gdal-grass: --with-grass=/opt/local/share/grass-7.4.0 requested, but libraries not found!

configure: error: --with-grass=/opt/local/share/grass-7.4.0 requested, but libraries not found!

The grass7 port currently installs version 7.8.6.

Looks like the +grass variant of the qgis port is also looking for grass 7.4.0 and is probably therefore also broken.

A procedure needs to be put in place so that this problem does not keep happening every time the grass7 port is updated. For example, a comment could be added to the top of the grass7 portfile to notify whoever updates it that corresponding changes are needed in gdal-grass, qgis, and qgis3. (qgis3 seems already to have been updated for grass 7.8.)

Nearly a year later, the problem still exists.

See: #64411

In 653a02384f0100ba0ee5eeabb58191f49cdc6d2b/macports-ports (master):

gdal-grass: adapt to being standalone GDAL driver

The "gdal-grass " GDAL driver has been split from GDAL and being made a
standalone driver at ​https://github.com/OSGeo/gdal-grass.

The version numbering is now separate from GDAL version and (re-)started from
1.0 (hence necessitated the setting of epoch).

Variants added:

• postgresql11-postgresql15
• grass

Variants removed:

• grass7

GRASS version detection is now done at build time.

Closes: #64411
