This has little to do with openssl itself, but I am familiar with such 
issues.
I'm using the same token with the same driver on CentOS 6, 7 and Fedora 
20/22 without and issues. Your problem could be caused by numerous 
incompatibilities:
- which version of opensc is installed
- which version of engine_pkcs11 and libp11 are installed
- which *exact* version of the eTPkcs11 driver are you using?

Keep in mind that for the latest OSes you will need the SafeNet client v9

HTH,
