Hi Giorgio,

I think I might be able to help you. I needed a complex digamma function 
  some time ago and wrote one myself because GSL doesn't provide one. I 
hope I'll manage to rewrite it in GSL style and contribute it
to GSL, but if you want, I could send you the source code before.

If you're interested, just tell me!

Cheers,

Frank
