julia_studio.sh gives a message that libExtensionSystem.so.1 cannot be found.

I tracked it down to the the "cd" command sometimes echoing the path when the CDPATH environment variable is set.

So, the line:
libdir=cd "$bindir/../lib" ; pwd

returns:
"/home/rod/develop/julia-studio/lib
/home/rod/develop/julia-studio/lib"

Adding:
unset CDPATH

prior to the libdir= .... fixed the problem.
