Sorry, but the output of --export was never compressed
in the first place.  It does a binary export of all public keys
in your keyring.  (compress-algo and -z have no effect in
this situation.)   You can do --armor --export  if you
want the output to be a non-binary ascii file (which you
can then compress), but --export already produces an
uncompressed binary file.  You would do:

   gpg  --export >mykeys.gpg
   gpg  -a --export >mykeys.asc
   gpg  -a -o mykeys.asc --export
