• requires SL5 amd64 kernel and userspace.
• requires GCC 4.3.2 (exactly this version!)
• new dead symlinks courtesy of Alexey; Derrick fixed these up in commit c696ca0bfd43d14e4bab4873a05c4baaafbe94f6 of boss-tools.

With Derrick's fix, the broken symlinks are exactly:

 lcg/external/{clhep,oracle,Grid}
 

The reason these can't also be automatically fixed is because these directories just don't exist here: Alexey is not distributing the clhep, oracle, or Grid packages.
