Condor on FC7

Trying to get condor running on a fresh Redhat Fedora Core 7. Got the following error while using the FC5 release from Condor:
[condor@localhost condor-6.8.5]$ ./sbin/condor_master
./sbin/condor_master: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

Luckily, just needed to add a compatibility library. First, used yum to install apt and synaptic:

yum install apt synaptic

Synaptic had a nice GUI but apt-cache was more my speed. I did have to update the file listings first ("reload" button on synaptic).

[root@localost ~]# apt-cache search libstdc++

Bang, condor_master now starts. Of course, I get the classic
[condor@localhost condor-6.8.5]$ ./sbin/condor_master
ERROR "The following configuration macros appear to contain default values that must be changed before Condor will run. These macros are:
hostallow_write (found on line 215 of /home/condor/Desktop/condor-6.8.5/etc/condor_config)
" at line 223 in file condor_config.C

I'm surprised the condor people don't post more warnings here. Just edit the condor_config file and change line 223 (should be obvious from the nearby comments).
