[BioC] load failed for 'Rlibstree'

[Paul Shannon]

While working my way through the rtracklayer pdf, I get stuck when 

  library (microRNA)

tries to load Rlibstree, with this error message:

  Loading required package: Rlibstree
  Error in dyn.load(file, DLLpath = DLLpath, ...) :
    unable to load shared library '/Library/Frameworks/R.framework/Resources/library/Rlibstree/libs/x86_64/Rlibstree.so':
    dlopen(/Library/Frameworks/R.framework/Resources/library/Rlibstree/libs/x86_64/Rlibstree.so, 6): Symbol not found: _lst_alg_longest_repeated_substring
   Referenced from: /Library/Frameworks/R.framework/Resources/library/Rlibstree/libs/x86_64/Rlibstree.so
   Expected in: dynamic lookup

  Error: package 'Rlibstree' could not be loaded

The package is installed (version 0.3-2) on my OS X 10.6.3 MacBook.

Any suggestions?  SessionInfo follows.

Thanks -
