[strongSwan] Cannot compile strong-swan from git

[Noel Kuntze]

Hello Ben,

I'm not a dev. I can only look at the source and give you advice on what probably helps.

The check for gperf seems to only soft fail. See configure.ac, line 378[1]:
# because gperf is not needed by end-users we just report it but do not abort on failure



Well, the end user would never run ./configure and devs need to compile it, so I don't understand the presumption given in the comment.

`in_word_set` is again a function that seems to be part of gperf. Maybe check what the configure script outputs. Maybe the gperf development headers are missing?

Kind regards

Noel
