source-highlight error after upgrade to 10.9

[Jean-François Caron]

Hi, I finally caved in and upgraded to 10.9 from 10.7 in order to get reasonable C++11 support.  One of the not-unexpected side-effects is random other problems coming up because of it.  

I have the environment variables LESS and LESSOPEN set for less to use source-highlight (e.g. http://superuser.com/questions/71588/how-to-syntax-highlight-via-less).  With the upgrade, now I get this error whenever I use less:

dyld: Symbol not found: __ZN5boost13match_resultsIN9__gnu_cxx17__normal_iteratorIPKcSsEESaINS_9sub_matchIS5_EEEE12maybe_assignERKS9_

I did rebuild all my ports after upgrading, and all the other ones that I tested work.  Is this because source-highlight is a GNU (thus libstcxx) program and 10.9 uses libcxx?  Or some other problem?
