root shared object libraries on Linux

I installed Root 5.18 from source on two different Linux machines, one running Debian Sarge (kernel 2.4.27-2-686) and one running Debian Etch (kernel 2.6.18-6-686). Both versions seem to run fine. However, in another application, one that includes a Tcl interpreter, I need to load a shared object library that in turn uses a Root shared library. The Tcl application library is called librootfilterformat.so, and, from within the Tcl interpreter window, the command:

load librootfilterformat.so

produces the error message:

couldn't load file
"/usr/opt/spectcl/3.2-001/TclLibs/librootfilterformat.so": /usr/opt/root/lib/root/libTree.so: undefined symbol: _ZN4TKey6BrowseEP8TBrowser  

It choked on an undefined symbol in the Root library, and does that on either version of Linux. If I do the following on that library:  

nm -demangle libTree.so,  

I get lots of undefined symbols. Is this normal, and, if not, did I overlook something in the Root build from source?  

Thanks.
