In the meantime I modified both glob.c and regexp.c to correctly handle [a-z] constructs and inserted some additional
#include's here and there. bjam builds itself correctly.
I also set up a the tool definition - os390xlc.jam in my case - and now I can use my existing Jamfiles to build
my own projects. This is already a great step forward!

But when I try to build boost libraries bjam only finds one target and does nothing. What do I do wrong? See output



> ./bjam

WARNING: No python installation configured and autoconfiguration

        failed. See
        for configuration instructions or pass
--without-python to

        suppress this message and silently skip all Boost.Python targets

Building the Boost C++ Libraries.

After the build, the headers will be located at


The libraries will be located at


Use 'bjam install --prefix=<path>' if you wish to
install headers and

libraries to a different location and remove the source tree.

...found 1 target...
