Working with V74_03_07

I'm having some problems getting the development tools built and installed.
The instructions on http://www.sapdb.org/develop/dev_linux.htm state that
after downloading and extracting the source, that DevTools/installtools.pl
should be run.  First, that file doesn't exist.  There is a
./sys/src/data/distribTools/installtools.pl.  Is that the correct one?

Next, when I run that code, I get complaints about the following directories
not existing:
./sys/src/data/distribTools/bin
./sys/src/data/distribTools/incl
./sys/src/data/distribTools/lib
./sys/src/data/distribTools/pgm

Once I did a "mkdir" for those directories, things started out better, but
then I ran into this:
# perl ./sys/src/data/distribTools/installtools.pl

Where is the program expecting to find iprofile?  What are the contents
supposed to be?
