[CentOS] SELinux : semodule_package, magic number does not match

Hello,

I am trying to create a custom policy, but with no succes :

$ cat <<EOF> foo.te
module local 1.0;

require {
        type httpd_sys_script_exec_t;
        type httpd_sys_script_t;
        class lnk_file read;
}

#============= httpd_sys_script_t ==============
allow httpd_sys_script_t httpd_sys_script_exec_t:lnk_file read;
EOF

$ checkmodule -M -m -o foo.mod foo.te
checkmodule:  loading policy configuration from foo.te
checkmodule:  policy configuration loaded
checkmodule:  writing binary representation (version 6) to foo.mod

$ semodule_package -o foo.pp -m foo.mod
$ echo $?
0
# So far, so good. But :

$ checkmodule -b foo.pp
checkmodule:  loading policy configuration from foo.pp
libsepol.policydb_read: policydb magic number 0xf97cff8f does not match 
expected magic number 0xf97cff8c or 0xf97cff8d
checkmodule:  error(s) encountered while parsing configuration
# And trying to "semodule -i foo.pp" fails completely.

So here come my questions :

- is there a boolean to allow httpd to execute a script "symlinked" ?
  (scontext=system_u:system_r:httpd_sys_script_t:s0
  tcontext=system_u:object_r:httpd_sys_script_exec_t:s0 tclass=lnk_file)
- can someone reproduce the error described above ?
- any clue on how to fix it ?

(For the curious one : I am fighting svn hooks on a filesystem
mounted "-o noexec".)
