proteinortho does not find diamon(-aligner) executable

[Steffen Möller <steffen_moeller@gmx.de>]

Hello,

I am just updating proteinortho and found that its tests look for a
series of binaries and executes the tests only if those binaries are in
the PATH. The diamond-aligner is a build package, likely for the reason
to be tested. The diamond-aligner's executable is also named
diamond-aligner - and not found.

Is this a bug of the diamond-aligner package to not offer some
compatibility layer or of proteinortho to use a non-standard executable
name? I'll team-upload proteinortho as it is now but something needs to
be done.

Cheers,

Steffen
