It has been repeatly reported that building gnupg 1.9.23 fails in the keyserver
part due to unresolved bugs.

This has already been fixed in SVN. A workaround is to either build without
gpg support or to manually add "-lgcrypt" to the link step. The actual
solution is to provide these symbols :-). We do this now the same way as in
tools/: A module no-libgcrypt.c is linked to each key helper.

We will do another release this week.
