perfsonar development work

This is the case at the moment. I have this as output:

[perfsonar@localhost
 ~]$ pwd
/home/perfsonar
[perfsonar@localhost
 ~]$ ls -l
total 18192

As you can see the symbolic link also belongs to the perfsonar user, yet 
when I try to go to that directory I get an error.

[perfsonar@localhost
 webapps]$ cd geant2_java-sshtelnet-mp
-bash: cd: geant2_java-sshtelnet-mp: No such file or directory

I tried going to that directory as root, and even this does not work. I 
get the same error.

[root@localhost
 webapps]# cd geant2_java-sshtelnet-mp
-bash: cd: geant2_java-sshtelnet-mp: No such file or directory

Tomcat also doesn't start the webservice, because it can't access that 
directory.

This is output of the machine I built the rpm on:

[perfsonar@localhost
 ~]$ ls -l
total 44
drwxr-xr-x  9 perfsonar perfsonar 4096 Feb  5 15:33 apache-tomcat-6.0.7
drwxr-xr-x 10 perfsonar perfsonar 4096 Feb  5 15:33

drwxr-xr-x  3 perfsonar perfsonar 4096 Feb  5 15:42 webapps
[perfsonar@localhost
 ~]$ cd webapps/
[perfsonar@localhost
 webapps]$ ls -l

lrwxrwxrwx 1 perfsonar perfsonar   57 Feb  5 15:42 
geant2_java-sshtelnet-mp -> 
/home/perfsonar/webapps/geant2_java-sshtelnet-mp-1.3-RC1/
drwxr-xr-x 4 perfsonar perfsonar 4096 Feb  5 15:41 
geant2_java-sshtelnet-mp-1.3-RC1

Once again, the symbolic link belongs to the perfsonar user. And here I 
can go into this directory using the perfsonar user:

[perfsonar@localhost
 webapps]$ cd geant2_java-sshtelnet-mp
[perfsonar@localhost
 geant2_java-sshtelnet-mp]$ ls
default.css               happyaxis.jsp  index.jsp     perfsonar_logo.gif
fingerprint.jsp           i18nLib.jsp    main.css      WEB-INF
geant2_java-sshtelnet-mp  index.html     partners.gif  wsdd

I use two different machines (both in VMware), the one I build the rpm 
on is Fedora Core 6, and the other one is Fedora Core 8. Does this make 
a difference?

The chmod command does not seem to work.

[root@localhost
 webapps]# chmod -R u+rw perfsonar:perfsonar ~perfsonar
chmod: cannot access `perfsonar:perfsonar': No such file or directory
