Thanks!!
I renamed the file and now it seems o.k.
I'm reporting all the steps I did in case they be
of help to others interested in PPCHTeX.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
System: Mandrakelinux 10.1 Community
When I installed Mandrake 10.1 Community, I chose the following
package installation:

- Office Workstation;
- Multimedia station;
- Internet Station;
- Configuration;
- KDE Workstation,

1) In www.google.com I typed `tetex', then went on the tetex official website: 
   http://www.tug.org/teTeX/, and from there downloaded the files: 
   tetex-src-3.0.tar.gz and tetex-texmf-3.0.tar.gz and copied them in my ~/tmp dir.

2) # urpmi flex
   , and Mandrake installed the package flex-2.5.4a-22mdk.i586.rpm;
   # urpmi bison
   , and Mandrake installed the packages
   bison-1.875d-1mdk.i586 and m4-1.4.1-1mdk.i586;
   # urpmi ed
   , and Mandrake installed the package ed-0.2-31mdk.i586.rpm;
   # urpmi gcc
   , and Mandrake installed the packages
   gcc-3.4.1-3mdk.i586 and glibc-devel-2.3.3-20mdk.i586;
   # urpmi gcc-c++
   , and Mandrake installed the package ed-0.2-31mdk.i586.rpm;
   gcc-c++-3.4.1-3mdk.i586 and libstdc++6-devel-3.4.1-3mdk.i586;
   # urpmi libncurses5-devel
   , and Mandrake installed the packages
   libgpm1-devel-1.20.1-11mdk.i586 and
   libncurses5-devel-5.4-1.20040529.1mdk.i586

3) From my ~/tmp dir I did: 
   # mkdir -p /usr/local/teTeX/share/texmf /usr/local/teTeX/share/texmf-dist
   # gzip -dc tetex-texmf-3.0.tar.gz \ | (umask 0; cd
/usr/local/teTeX/share/texmf-dist; tar xvf -)
   , then removed the file tetex-texmf-3.0.tar.gz from my ~/tmp dir.

4) From my ~/tmp dir,
   $ tar xzvf tetex-src-3.0.tar.gz
   $ cd tetex-src-3.0
   $ ./configure
   $ make
   # make install
   , then removed from ~/tmp the file tetex-src-3.0.tar.gz
   and the whole directory tetex-src-3.0.

5) $ mkdir /home/rodolfo/bin
   $ echo $PATH
   , and I got the following output:
   /usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/games:/home/rodolfo/bin
   , so I did:
   $ export
PATH="/home/rodolfo/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/games"
   , and then
   $ cd /home/rodolfo/bin
   $ ln -s /usr/local/teTeX/bin/i686-pc-linux-gnu/tex tex

6) In my home dir I created the file `myfile.tex' 
   (ATTENTION: don't call it ppchtex.tex!), and typed in it the following:

   \input m-pictex.tex 
   \input m-ch-en.tex

   \startchemical
	[size=big,width=6000,height=6000,frame=off,axis=off]
	\chemical[SIX,SB2356,DB14,Z2346,SR36,RZ36]
	  [C,N,C,C,H,H_2]
	\chemical[PB:Z1,ONE,Z0,DIR8,Z0,SB24,DB7,Z27,PE]
	  [C,C,CH_3,O]
	\chemical[PB:Z5,ONE,Z0,DIR6,Z0,SB24,DB7,Z47,PE]
	  [C,C,H_3C,O]
	\chemical[SR24,RZ24]
	  [CH_3,H_3C]
   \stopchemical
 
   \vfill\eject
   
   , then did: `$ tex myfile'.
