fatal: can't create directory `//.gnupg': Permission denied

[Dr. Blunt]

I can manually run the php script but cannot run it as a cron.
I am logged in as the owner of the script... Can you point
in the right direction. Thanks

This is the error:
gpg: fatal: can't create directory `//.gnupg': Permission denied
secmem usage: 0/0 bytes in 0/0 blocks of pool 0/32768
