I have never used pgp. I use gpg instead and I'll bet that most people here do as well. Since pgp is a product maybe you can get support from the manufacturer.
But just a few guesses based on how gpg behaves... I cannot believe that root is required. That would be a very bad design decision. I can create a key with gpg and see it immediately with the --list-keys option. The key is created in files that reside in .gnupg. I need to be able to write to those files. pgp, while it probably uses different names, probably also stores stuff in files and thus needs to write to those files. So I guess I would check that.

gpg-preset-passphrase
GPG-PRESET-PASSPHRASE(1) GNU Privacy Guard GPG-PRESET-PASSPHRASE(1)
NAME
gpg-preset-passphrase - Put a passphrase into gpg-agent's cache
SYNOPSIS
gpg-preset-passphrase [options] [command] cache-id
DESCRIPTION
The gpg-preset-passphrase is a utility to seed the internal cache of a running gpg-agent with passphrases. It is mainly useful for unat-
tended machines, where the usual pinentry tool may not be used and the passphrases for the to be used keys are given at machine startup.
Passphrases set with this utility don't expire unless the --forget option is used to explicitly clear them from the cache --- or gpg-agent
is either restarted or reloaded (by sending a SIGHUP to it). It is necessary to allow this passphrase presetting by starting gpg-agent
with the --allow-preset-passphrase.
gpg-preset-passphrase is invoked this way:
gpg-preset-passphrase [options] [command] cacheid
cacheid is either a 40 character keygrip of hexadecimal characters identifying the key for which the passphrase should be set or cleared.
The keygrip is listed along with the key when running the command: gpgsm --dump-secret-keys. Alternatively an arbitrary string may be used
to identify a passphrase; it is suggested that such a string is prefixed with the name of the application (e.g foo:12346).
One of the following command options must be given:
--preset
Preset a passphrase. This is what you usually will use. gpg-preset-passphrase will then read the passphrase from stdin.
--forget
Flush the passphrase for the given cache ID from the cache.
The following additional options may be used:
-v
--verbose
Output additional information while running.
-P string
--passphrase string
Instead of reading the passphrase from stdin, use the supplied string as passphrase. Note that this makes the passphrase visible
for other users.
