[R-SIG-Mac] BWidget missing

[Denis Chabot]

Hi,

I installed all that was available when I installed R 2.9.2, including  
tcltk. However, I got this message upon loading PBSmodelling.

I had a quick look at what Google found but it seems that I'd have to  
install this from source. Why would this particular part of tcltk need  
to be installed manually while the rest seems to be pre-installed  
(with the OS? by the R installer?).

Thanks in advance,

Denis Chabot
