it can be, 
but only if the gnupg user uses the option of
'--pgp6'

pgp 6.x is relatively old,
and does not include AES (Rijndael) or Twofish

if the gnupg user, by default uses AES
(as is quite likely)

then pgp6.x will not be able to decrypt


am curious,
why are you still using pgp 6.5.2 ?

is it because you have commandline pgp 6.5.2 ?

if you like/need commandline,
gnupg commandline is incomparably better!
(and free ;-)  )

if not,
and your staff is just 'comfortable' with pgp
you might try using the latest version of pgp 8.x
(available at zedz)
which has the 'feel' of 6.5.2
but allows for AES and TWOFISH

(even with pgp 8.x
you should caution gnupg users to use the option of
'--pgp8'
otherwise you might not be able to verify their signatures using 
SHA-512
(or, less likely, SHA 224 or 384))
