Your subject line is (perhaps) a bit misleading: this seems to be
nothing specific to the use of jails, but due to having sym-links in
various paths.  It could happen just the same if you laid out your host
filesystem using sym-links.

Anyhow, this looks like a bug to me -- using sym-links to put your
filesystem together should not result in chaos.

Are you using pkg(8)?  There are differences in the way a package is
generated from the staging directory between pkg(8) and pkg_create(1)
which might make all the difference.

Is it all ports that are affected?  Does the use of PLIST_FILES or
PLIST_DIRS in the port Makefile make any difference compared to having a
pkg-plist file?

A possible work-around: instead of sym-linking /s/usr-local ->
/usr/local use a nullfs mount instead.

    mount -t nullfs /s/usr-local /usr/local

(Actually, you'ld probably do that from outside the jail so adjust the
paths accordingly.)

Another workaround:  set up your own poudriere instance to build
packages for all your jails.  poudriere(8) will create its own jails to
do package building in, and manage paths etc. itself.  It's a natural
partner to pkg(8) and zfs(8) but it will work without either of those.

	Cheers,
