According to the ebuild's DEPEND, dev-libs/libksba-1.0.0 depends on >=libgpg-error-0.7, but configure checks for >=1.2 and fails: checking for gpg-error-config... /usr/bin/gpg-error-config checking for GPG Error - version >= 1.2... no configure: error: libgpg-error is needed. See ftp://ftp.gnupg.org/gcrypt/libgpg-error/ .
Thanks! Fixed.
