unable to execute program `gpgkeys_hkp': Permission denied

[Adam Funk]

I compiled and installed GnuPG 1.4.0.  Everything works except interaction 
with keyservers.  When I use --send-key, --recv-key or --refresh, it 
always fails thus:

$ gpg -v --recv-key F09BDAD5
gpg: requesting key F09BDAD5 from hkp server pgp.mit.edu
gpg: unable to execute program `gpgkeys_hkp': Permission denied
gpg: keyserver internal error
gpg: keyserver receive failed: keyserver error

How do I fix this?

Thanks,
Adam
