Dear Chimera developer,

I am trying to install UCSF-Chimera and I have an issue with the 
libXext.so.6 library

I 've installed the library package that contains this and I can locate 
it at:


However I get this error:

Install desktop menu and icon? yes

If I install it in the default Chimera directory without desktop icon it 
proceeds to the installation but I can not run chimera - taking the same 

ImportError: libXext.so.6: cannot open shared object file: No such file 
or directory

Any suggestions how to solve it? Should this be linked to somewhere else 
in order the Chimera to find it?

Thank you very much in advance.

Best regards,
