CGI scripts (running as httpd_sys_script_t) shouldn't be prevented from
using /tmp; this macro in macros/apache_macros.te allows it:
file_type_auto_trans(httpd_$1_script_t, tmp_t, httpd_$1_script_rw_t)

Hmmm. httpd_tmp_t is the type of temporary files generated by the main
webserver, not by CGI scripts. Perhaps what's happening is you have
some PHP code which is using aspell and creating a temporary file in the
main httpd process, and then a CGI script wants to read that later?
Hard to say without knowing more details about how aspell works.
