GRASS fails to compile with libpng 1.5

[aaschwanden (Andy Aschwanden)]

Upgrading GRASS fails for me during compilation, see error message below. Cleaning the port and re-installing leads to the same error:

In case of errors please change into the directory with error and run 'make'.
If you get multiple errors, you need to deal with them in the order they
appear in the error log. If you get an error building a library, you will
also get errors from anything which uses the library.

Error: Processing of port grass failed

As suggest above, I tried:

$ cd /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_gis_grass/grass/work/grass-6.4.0/raster/
$ sudo make

and it worked without breaking. Then I did:

$ cd ..
$ sudo make

and compilation failed with (again):

Now upon closer inspection of the log file, I find:

Any suggestions?

Thanks in advance,

Please remember to use WikiFormatting when writing in Trac.

As we're discovering with lots of other ports too, this version of grass is incompatible with libpng 1.5. We'll need to update grass or patch it.

Fixed in r97442 by updating to 6.4.2.
