Problems linking under RedHat Linux 5.2

I've just started to try to port some of my root programs from Windows95
to Linux.  I took the makefile in the "test" subdirectory of the root
(2.00/8) release and modified it for my program.  This same program has
been successfully compiled, linked, and run under Windows95.  When I try
to build it under Linux I get the following error message:

[dfnitz@auger3 trigger_sim]$ make
g++ -g fast_trg_bkg.o AUGERFastTrg.o AUGERFastTrgCint.o \
-L/usr/local/cern/root/lib -lNew -lBase -lCint -lClib -lCont -lFunc -lGraf

-lTree -lUnix -lZip -lg++ -lm -ldl -rdynamic -o fast_trg_bkg
AUGERFastTrgCint.o: In function `AUGERFastTrg type_info function':

This is my Makefile:

SrcSuf        = cxx
ExeSuf        =
DllSuf        = so

ROOTLIBS      = -L$(ROOTSYS)/lib -lNew -lBase -lCint -lClib -lCont -lFunc \
                -lGraf -lGraf3d -lHist -lHtml -lMatrix -lMeta -lMinuit -lNet \
                -lPostscript -lProof -lTree -lUnix -lZip
ROOTGLIBS     = -lGpad -lGui -lGX11 -lX3d

# Linux

CXXFLAGS      = -O -Wall -fPIC -I$(ROOTSYS)/include

SOFLAGS       = -Wl,-soname,libEvent.so -shared

                -lXpm -lX11 -lg++ -lm -ldl -rdynamic

AUGERFastTrgCint.cxx:   AUGERFastTrg.h		      
	@echo "Generating dictionary ..."
	@rootcint -f AUGERFastTrgCint.cxx -c  AUGERFastTrg.h

Any suggestions?
