From github issue:

The voms-2.0.pc file contains

Requires: openssl
which causes our build of liblcmaps to include -lssl on the link line. The resulting binary will have an unnecessary link to libssl (as reported by ldd

[root@fedora19 ~]# ldd -r -u /usr/lib64/liblcmaps.so
Unused direct dependencies:
/lib64/libssl.so.10
The above line should rather read:

Requires.private: openssl
