If you're using 2.0-m10, you need to add "path-constant" invocation to 
project-root.jam.

path-constant BIN_ROOT : whatever ;

If you're using CVS version, you can add this either to project-root.jam orto 
Jamfile. In fact, you better have one file called Jamroot at top-level, and 
don't bother with difference between project-root.jam and top-level Jamfile.

project Project2
: requirements <dependency>..//Project2 
;

might be enough?

You can check for directory existence with the glob rule.

Jamfile:

if [ glob ../Project1 ] 
{
.........
}

The argument to 'glob' is a pattern relative to Jamfile location.
