Best solution would IMHO be to include the (empty) directory in the
package tree so that dpkg takes care of creating and removing the
directory. Then, you can generate the byte-compiled files in the postinst
script and should remove them in the prerm script (not postrm!).
This way, the directory will not be wiped away if some other package (or
the sysadmin) placed some files there.
(Note, that I can't comment on whether you should ship byte-compiled files
or compile them on demand. You would have to give us a little more info
about which files these are, how long compilation takes, etc.)
Thanks,
