[R-SIG-Mac] tcltk not working in R 3.1.1 on MacOS X 10.9.2

[Yampolsky, Lev]

Dear Colleagues,

Attempts to use tcltk (R 3.1.1  on MacOS X 10.9.2) or any dependent library (for example qvalue) results in:

> library(tcltk)
Error : .onLoad failed in loadNamespace() for 'tcltk', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.1/Resources/library/tcltk/libs/tcltk.so':
  dlopen(/Library/Frameworks/R.framework/Versions/3.1/Resources/library/tcltk/libs/tcltk.so, 10): Library not loaded: /opt/X11/lib/libX11.6.dylib
  Referenced from: /Library/Frameworks/R.framework/Versions/3.1/Resources/library/tcltk/libs/tcltk.so
  Reason: image not found
Error: package or namespace load failed for ‘tcltk’

Tried:
- upgraded to the most recent R (it did say at installation that it includes tcltk)
- manually upgraded tcltk to tcltk 8.6.1

Neither helped. A few discussions I read imply that I should not do anything and R ver3 or more recent should come bundled with tcltk and it should work.

Any ideas?

Thanks very much in advance,
