[R-SIG-Mac] Installing packages from .gz files

[Tim Cole]

I've been given an updated version of the gamlss package as a .tar.gz 
file, but I'm struggling to install it with the package installer. I 
specify Local Binary Package at the top, but when I Install and 
select the file I get errors whichever of the three possible files I 
point to - the .tar.gz file or .tar file or the gamlss folder. What 
am I doing wrong?

The .gz file error is:
Error in gzfile(file, "r") : unable to open connection
In addition: Warning message:
cannot open compressed file 'gamlss_1.4-6.tar.gz/DESCRIPTION'

Thanks,
Tim Cole
