[ROOT] Problems with TFile and dlopen

Hi - (using ROOT 3.03/06) I have a selector that I execute using:

 ntp1->Process("esigtightplots.C++");

where ntp1 is a TChain.

In my selector, esigtightplots, I have the following line in my terminate
method():

TFile myOutputFile("esigtightplots.root","recreate");

I get the following message when I process:

dlopen error: /data1/babar/edward/root/./esigtightplots_C.so: undefined
symbol: __5TFilePCcPCcT1i
Load Error: Failed to load Dynamic link library
/data1/babar/edward/root/./esigtightplots_C.so

If I change the line to:

TFile myOutputFile;

I do not get the error message.

Any idea what's going on?  Thanks.

-Ed
