There are two issues at play here: Lion's install process, and the
stability of PGP on Lion in general.
As to the former issue: when installing Lion, the installer creates a
recovery partition, which allows disk repair/restore without the need for
install media, which Apple no longer includes. This partition is also
required to make use of Apple's built-in FileVault 2 whole disk encryption
software. If Lion is unable to create this partition during the
installation process, it will display the "some features are not
supported" message. This KB article explains in more depth:
Is it possible to install/run OS X 10.7 Lion without the recovery
partition? Yes. Most software will run fine without it (except FileVault
2, which won't run at all), and you'll only be missing on-board tools to
reinstall Lion or run Disk Utility or reset firmware passwords. This
generally isn't an issue if you maintain your own backups and are willing
to have the machine wiped/reimaged to reinstall Lion if needed (I should
probably note here that the Depot's Lion imaging process does create the
recovery partition when performed).
As to the latter issue: as Andrew and Jim have already stated, PGP on Lion
is not yet supported by Symantec. If you plan to continue to run PGP, it
is recommended to stick with Snow Leopard.
