Either that, or modify the variable ODE_BASE in the setup script.

I have updated the file INSTALL that mentions the distutils now.

Agreed. However, I don't know what the "official" way is to introduce 
new options to the setup script. There's the possibility to have a 
setup.cfg file where you can keep default parameters that can also 
modified on the command line, but I haven't seen anything that lets me 
define new parameters.

By the way, what's the preferred location for the ODE include files and 
libs on Linux? Should the script use something like /usr/include and 
/usr/lib as default paths? Or do you actually keep ODE in a separate 
directory?

And another thing, I just realized that since Pyrex 0.9.3 we don't have 
to parse the ODE user-settings file anymore because it finally puts the 
typedef name into the generated C file. This means wherever "dReal" is 
used in the *.pyx file it will remain "dReal" in the C file and will not 
be replaced by "float" or "double". So we don't have to care anymore if 
ODE was compiled using single or double precision. We will automatically 
use the correct precision.
I'll commit the modified setup script later today. Or are there any 
objections (i.e. is there a reason why you can't upgrade to Pyrex 0.9.3)?

> or simply whether the user wants it to be compiled with double or float precision 

This decision is already made when ODE itself is compiled. There's no 
choice anymore for PyODE. But as I said above, with Pyrex 0.9.3 all this 
is obsolete anyway.
