After Installation of Yosemite some command line tools not found! I just did a clean installation of 10.10. 
Now some command line tools won't work anymore.
In example gshred is not found anymore (always worked on Lion) and man gpg gives
"No manual entry for gpg".

Has anyone an idea what the problem might be? :)
GPG for Mac can be found at:
https://gpgtools.org/

Your problem description also means, if not using some PKI infrastructure, you lost your PGP keys...
