Any SELinux messages should be in /var/log/audit/audit.log, assuming there's
nothing like bad contexts on installed files which can be corrected with
restorecon, then you can use the audit2allow command on those log lines (you
only want those related to mapnik), something like 'grep mapnik
/var/log/audit/audit.log |audit2allow -M mapnik', this will create a
mapnik.pp file in the current directory, this can be installed by running
'semodule -i mapnik.pp'... You'll probably find it easier to set SELinux to
permissive mode, run through your test cases, build and install the policy
module, set SELinux back to enforcing mode and give it a try... All being
well with the policy module, this could be included in the mapnik package...

Hope this helps...
