I still don't know what's causing your problem, but here's something you can try:
- at the command line, type
nano ~/.cshrc
- in the editor, type
set path = ( $path $HOME/abin/macosx_10.7_Intel_64 )
setenv DYLD_FALLBACK_LIBRARY_PATH $HOME/abin/macosx_10.7_Intel_64
(or copy-paste from this forum)
- type CTRL-O to save
- hit ENTER to accept the file name listed near the bottom of the screen (which will be something like /Users/Sampada/.cshrc)
- type CTRL-X to exit
- now try
source ~/.cshrc
at the command line.
P.S.: I was going to tell you to use TextEdit for this, but the amount of configuration you would have to do to be sure it wasn't breaking things is absurd. Using TextEdit for scripts is asking for trouble.
