[gmx-users] ngmx,dssp not working

[sharada]

Dear gmx-users,
I have installed the gromacs 3.3.3 on a dual core HP workstation with Ubuntu platform. All the programs are properly installed and working except ngmx and dssp. However there is a difference, ngmx is not  installed as I donot see the link in /usr/local/bin along with the other programs. where as dssp when  executed   outputs one pdb file and  just hangs for a long  time (days) without giving  any  other output.  This is how the output looks:
-==============================================
Option       Type   Value   Description
------------------------------------------------------
-[no]h       bool   no      Print help info and quit
-nice        int    19      Set the nicelevel
-b           time   0       First frame (ps) to read from trajectory
-e           time   0       Last frame (ps) to read from trajectory
-dt          time   0       Only use frame when t MOD dt = first time (ps)
-tu          enum   ps      Time unit: ps, fs, ns, us, ms or s
-[no]w       bool   no      View output xvg, xpm, eps and pdb files
-[no]xvgr    bool   yes     Add specific codes (legends etc.) in the output
                            xvg files for the xmgrace program
-sss         string HEBT    Secondary structures for structure count

Back Off! I just backed up ddIuI8uU to ./#ddIuI8uU.1#
=================================================
I am unable to figure out the problem. Any suggestions are welcome.  About ngmx I tried to install it seperately using make and make install but it does not compile/install. How should I install it ? Thankyou for the time.
