:SELinux is preventing /sbin/ldconfig from 'write' accesses on the directory /var/cache.
:
:*****  Plugin catchall_labels (83.8 confidence) suggests  ********************
:
:If you want to allow ldconfig to have write access on the cache directory
:Then you need to change the label on /var/cache
:Do
:# semanage fcontext -a -t FILE_TYPE '/var/cache'
:where FILE_TYPE is one of the following: user_home_t, ld_so_cache_t, var_lib_t, ldconfig_tmp_t, ldconfig_cache_t, lib_t, tmp_t, etc_t, user_tmp_t, rpm_script_tmp_t. 
:Then execute: 
:restorecon -v '/var/cache'
:
:
:*****  Plugin catchall (17.1 confidence) suggests  ***************************
:
:If you believe that ldconfig should be allowed write access on the cache directory by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep ldconfig /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

9920aa7c4ee32b3d4fb4e67a3300e8f27e729c61 fixes this in Fedora 17

mkdir /var/cache/ldconfig
