Windows, I presume.

What does 'try' mean?  That would work if you used Rcmd INSTALL on it, 
or install.packages(type="source").

Why from 2.7?  What version is your R?

So that worked: it is 'proxy' you are missing.  From the DESCRIPTION 
file

package: tm
Title: Text Mining Package
Version: 0.3-3
Date: 2008-12-20
Author: Ingo Feinerer, with contributions from Christian Buchta, Kurt 
Hornik, David Meyer, and Fridolin Wild
Maintainer: Ingo Feinerer <feinerer at logic.at>
Depends: R (>= 2.7.0), filehash, Matrix, methods, Snowball, XML
Imports: proxy
Suggests: Rgraphviz, Rmpi, Rstem (>= 0.3-1), snow

still you may need packages filehash, Matrix, methods, Snowball and 
proxy.

I suggest getting those from bin/windows/contrib/2.7/ on CRAN, and 
installing from the 'Local zip file' menu optipn.

Read the posting guide, remember to tell us what we asked for 'at a 
minumum' and what you actually did.
