[ESPResSo] Installation Question

[Lorenzo Isella]

Dear All,
I have downloaded the espresso tar.gz file and installed Espresso, but I 
am having some problems to run the tutorial.
I am running Debian testing on my box.
I unzipped the Espresso source, and from the newly created folder I 
entered the command:
./configure CPPFLAGS=-I/usr/include/tcl8.4 --without-mpi
which produced a lot of output; here I report only the configuration 
summary:

*                   Configuration summary                      *
****************************************************************
platform detected       = Pentium_M-pc-linux

Compiler settings:
------------------
MPI                     = fake
compiler                = gcc
linker                  = gcc
c compiler flags        = -finline-limit=1000000 -fomit-frame-pointer 
-funroll-loops -floop-optimize -ffast-math -Wall -Wno-unused-function 
-O3 -malign-double -msse2 -mfpmath=sse -march=pentium-m -m32
c preprocessor flags    = -I/usr/include/tcl8.4
linker flags            =
libraries               = -lfftw -ltcl8.4  -lrfftw -lfftw
using debug flags       = no
using profiling flags   = no
inline                  =

Libraries:
----------
Tcl version             = tcl8.4
Tk version              = none
FFTW version            = 2
efence                  = no

Other settings:
---------------
using Espresso chooser  = yes
local config header     = myconfig.h
pdflatex                = /usr/bin/pdflatex
doxygen                 = no

Then I ran the make command, which did not return any error message.
Finally, instead of make install, I used checkinstall (Debian tool to 
create a Debian package which integrates better into the system), which 
returned:
**********************************************************************

Done. The new package has been installed and saved to

/home/iselllo/internet-download/Espresso/espresso_2.3-1_i386.deb

You can remove it from your system anytime using:

     dpkg -r espresso

**********************************************************************

So everything should be fine. In fact, I tried launching espresso from 
the directory where I built everything:
$ ./Espresso
0: Script directory: 
/home/iselllo/internet-download/Espresso/obj-Pentium_M-pc-linux/../scripts

*******************************************************
*                                                     *

* Mainz, Germany                                      *
*                                                     *

However, when I tried running the tutorial, this is what I got:

./Espresso samples/tutorial.tcl
0: Script directory: 
/home/iselllo/internet-download/Espresso/obj-Pentium_M-pc-linux/../scripts

Should I change the value of that variable? Or did I do anything wrong 
with my installation?
Actually, after the installation I see a newly created folder containing 
the espresso binary, but nothing changes when I use that to call the 
tutorial. Sorry for my newbie's question, but I am new to espresso and 
molecular dynamics in general (actually I was suggested espresso after 
posting on the gromacs list).
Many thanks
