[R-SIG-Mac] tar not found

[Carl Witthoft]

I'd grab the source to install.packages and see if for some reason 
there's a hard-coded path to tar.
Not that I'm a highly skilled coder, but I sure would have hoped that 
the author of install.packages would at least have made sure that,if 
it's calling system functions (like /bin/sh), it would make sure to pick 
up the user environment -- not just grab the R console's idea of the 
environment.


Here an error. This installation usually does work...
