GnuPG 2.0 compilation fails with "undefined reference to gpg_err_code_from_syserror"

[Ralph Seichter]

Hi list,

I'm having trouble compiling the "agent" component of GnuPG 2.0 on a
Gentoo-based machine. I could not find anything about the error message
(please see attachment) in the FAQ or by searching the Net, so I hope
that the members of this mailing list are able to help.

If you need any information about the machine on which I am trying to
build GnuPG 2.0, please let me know. As a preparation, I have built and
installed libgpg-error 1.4, libassuan 1.0.1 and libksba 1.0.0, but
perhaps there is still something missing?

Your help is appreciated.
