installation issue

Hi,
I got stuck when i run following command ( it is written in installation tutorial "source your ~/.bashrc file with the command:source ~/.bashrc"):

source ~/.bashrc

It can not do anything in terminal and then i can not open terminal later.
When i delete multiple lines written in bashrc then I can use terminal again. These multiples lines are :

#- source OpenFOAM-1.7.x
. $HOME/OpenFOAM/OpenFOAM-1.7.x/etc/bashrc
#- enable parallel compiling
export WM_NCOMPPROCS=2
#- source OpenFOAM-1.7.x
. $HOME/OpenFOAM/OpenFOAM-1.7.x/etc/bashrc
#- enable parallel compiling
export WM_NCOMPPROCS=2
.

Please anybody help me...
Thanks
Ram
