We used the default pcsclite since horizon linux agent 8.7 instead of pcscd 1.8.8. In another word, since horizon linux agent 8.7, the code for pcscd 1.8.8 don't need to be downloaded and built.
If you want to upgrade horizon inux agent 8.8 from agent 8.6, you should uninstall the pcsclite you built. And then reinstall the default libraries via 'yum reinstall pcsc-lite-libs pcsc-lite'. After that, you install the horizon linux agent.
