I am having trouble running aplpack on my Mac. It will run on my PC, but 
the Mac gives an error message. Below is the result that I obtained.  It 
seems to install fine--see below--but I can't load the library.


 > install.packages("aplpack")
trying URL 
'http://cran.rstudio.com/bin/macosx/contrib/3.1/aplpack_1.3.0.tgz'

The downloaded binary packages are in
/var/folders/6m/t4wvnh9x39500z_rh3p5jlk00000gp/T//Rtmp26I5Ej/downloaded_packages

 > library(aplpack)
Loading required package: tcltk
xcrun: error: invalid active developer path 
(/Library/Developer/CommandLineTools), missing xcrun at: 
/Library/Developer/CommandLineTools/usr/bin/xcrun

It looks as if it has a problem with tcltk. I can install tcltk2, but 
when I try to install tcltk it tells me "package not found.) Is that the 
problem that aplpack is having when it tries to load the library?

Any suggestions?
