[R] Can not install fCalendar package under R 2.6.2

[Yan Wang]

Dear R helper:
When I was trying to install the fCalendar package, R report the 
following error and then my installation failed:

* Installing *source* package 'fCalendar' ...
** R
** inst
** preparing package for lazy loading
Loading required package: MASS
Loading required package: fEcofin
Loading required package: fUtilities
Loading required package: RUnit

  RUnit 0.4.17 loaded.
Loading required package: spatial
Loading required package: tcltk
Loading Tcl/Tk interface ... done
Loading required package: zoo
Error in .Internal(putenv(x)) : no internal function "putenv"
Calls: <Anonymous> ... sys.source -> eval -> eval -> .currentYear -> 
Sys.setenv
Execution halted
ERROR: lazy loading failed for package 'fCalendar'
** Removing '/usr/local/lib/R/site-library/fCalendar'

by the way, my system is Ubuntu 7.04,
platform       i486-pc-linux-gnu
arch           i486
os             linux-gnu
system         i486, linux-gnu

I tried to look for  putenv myself, R reported that it is a deprecated 
function in "base" package, I loaded the "base" package and still end up 
with the same Error report.

Pls do help me.
