New ABF order parameters

Dear ABF and NAMD developers,

I downloaded the files dihedral.tcl and dihedral-com.tcl into ~/NAMD_2.6_Linux-i686/lib/abf from the ABF website. Do I need to do any thing else to use these new order parameters?

When I run a test job with "abf coordinate dihedral", it dies with the error:
TCL: Unknown ABF keyword: abf3
FATAL ERROR: Unknown ABF keyword: abf3.

Here is the ABF part of my conf file:
#######################################################
## ABF ##
#######################################################
if {1} {
source ~/NAMD_2.6_Linux-i686/lib/abf/abf.tcl
abf coordinate dihedral
abf abf1 {6}
abf abf2 {8}
abf abf3 {14}
abf abf4 {16}
abf dxi 0.1
abf xiMin 0.1
abf xiMax 179.9
abf outFile abf_AA.pmf
abf historyFile abf_AA.hist
abf fullSamples 200
abf inFiles {}
abf dSmooth 0.0
abf restraintList {}
#######################################################
Any help in fixing this problem is much appreciated.

thanks,
Vaithee
