As the error says, a friend declaration specifying a default argument must also be a definition. Newer versions of clang will choke on this because these friend declarations specify default arguments but are not full function definitions (no body).

Full discussion of this issue can be found ​here and some alternative fixes for this type of issue are discussed ​here.

This issue should probably be referred to the upstream developers for resolution since choosing the correct fix requires some understanding of the related code.

Actually, I see that version 3.0.0 of this port and it's dependencies are now available. Updating now to see if that effects this issue.

[dbevans (David B. Evans)]

dependency libghemical updated to version 3.0.0 in r139540.
dependency liboglappth updated to version 1.0.0 in r139541.

ghemical updated to version 3.0.0 in r139542 using patch from ​debian bug 756440 which fixes the clang build issue reported here.
