There are two ways to disable this message:

If you have root access to the gpg executable then you can change gpg to be

chmod 4755 gpg

there is also an option --no-secmem-warning that is documented in the manual

Basically, what this warning is telling you is that gpg is unable to lock=
memory for the exclusive use of gpg (ie, no other programs/processes/etc)
can inspect the state of the program and it's internal data.  if the box th=
you are using is private (like your own linux box) then this warning has le=
meaning than if you are running gpg on your ISP's box w/ 300 different user=

=46rom a security standpoint, any possible way that your data can be potent=
exploited should be reported, and gpg is doing a good job of telling you
about it.

Hope this helps.
