Pythia6 problem on Mac OS X Tiger

Hello,

I compiled root and pythia6 on my Mac. All seemed to work fine until I tried compiling my pythia code which contains references to pythia6. This is what I see:

The pythia6 library preparation goes nicely: maku:~/Downloads/pythia6 toruonu$ sh makePythia6.macosx pythia6319.f: In block-data unit `pydata': pythia6319.f:315: warning:

ar: creating archive libPythia6.a

a - main.o
a - tpythia6_called_from_cc.o
a - pythia6319.o
a - pythia6_common_address.o

so the libraries are created. However if I now try to compile my program:
g++ `root-config --cflags --libs --glibs` -lPythia6 -lEG -lEGPythia6 - o higgsanal higgsanal.C
/usr/bin/ld: Undefined symbols:
_tpythia6_close_fortran_file
_tpythia6_open_fortran_file
collect2: ld returned 1 exit status

what could be the problem??? I'm not that fluent in MacOS so if it's just some stupid thing I have to do with the library or is there something more? The libPythia* files are in ROOTSYS/lib directory.

And when I run the code interactively:
maku:~/pythia toruonu$ root -l
root [0] .x higgsanal.C
Error: Function higgsanal() is not defined in current scope :0: Possible candidates are...
filename line:size busy function type and name *** Interpreter error recovered ***
root [1] .L higgsanal.C
root [2] loadLibraries()
Note: File "/Applications/root/lib/libPhysics.so" already loaded root [3] GenPlots("data/h200_20k_2mu2tau.root","test.root",50,2.5,2) Event #0

Total number of events: 20000
Total number of H++/H-- candidates found: 17918 root [4]

then it works...
