[R] Problem compiling R - "use of NULL environment is defunct"

[Saptarshi Guha]

Hello,
I downloaded R-2.5.1 and configured it on a AMD x86-74 running  
Redhat. During compilation i get this error

configure --prefix=$HOME/mine
make

mkdir -p -- ../../../../library/methods/libs
make[5]: Leaving directory `/home/sguha/tmp/R-2.5.1/src/library/ 
methods/src'
make[4]: Leaving directory `/home/sguha/tmp/R-2.5.1/src/library/ 
methods/src'
make[4]: Entering directory `/home/sguha/tmp/R-2.5.1/src/library/ 
methods'
dumping R code in package 'methods'
Error in `parent.env<-`(`*tmp*`, value = NULL) :
         use of NULL environment is defunct
Execution halted

Could someone point out what I'm supposed to fix?
Thank you for your time
