non-ciritcal error during TP 4.6.1 install on centos 6.3?

[Gautam Saxena]

In building  TPP 4.6.1 on centos 6.3, I encountered this error (highlighted in red):

.... {1000s of previous lines not shown} 

cp -f ../schema/msms_analysis3.dtd /usr/local/tpp/schema/

chmod: cannot access `/usr/local/tpp/bin/bin': Too many levels of symbolic links                                                
make: *** [install-linux-xml] Error 1  make: *** [install-linux-xml] Error 1 

However, I just chmod 777 -R the /usr/local/tpp directory, and it din't complain. Then, I deleted the offending link in the tpp folder (it was a weird "bin" folder that was linked to itself"). I ran ./tandem.sh and it gave me the normal greeting message etc.

Is this ok? Is this "normal" behaviour? Why do we have circular links?

Note: The only thing that I definitely did different was that I did NOT create the " /usr/local/src/TPP-4.5.2/src/Makefile.config.incl" file specified here: http://tools.proteomecenter.org/wiki/index.php?title=TPP_4.5.2:_Installing_on_Ubuntu_10.04.3

I did have, though, the boost libraries seemingly installed in the default distribution of centos 6.3 and they were relatively recent. Is this makefile.config.incl asbsolutely required? (I didn't include it because I had a hard time figuring out what should be the location for my boost libraries -- I couldn't find exact corresponding entries, so I thought I'd first see if this file was truly needed.....). Since the make kept going, I'm assuming that I didn't run into any serious and/or fatal errors....and I don't think this lack of makefile.config.incl is related to teh "Too many levels of symbolic links" errors, above, right?
