Cau Jurko,

Thanks for your reply.

Yes it is not self-contained, I am sorry about that. I spend some time
making it a small self-contained project, but then the bjam-problem
goes away mistereously...

Hmmmm that is strange. I have problems with the INSTALL_PATH  variable
defined in Jamroot. In Jamfiles I use this in install command like
this:

install $(INSTALL_PATH)/htbin : nph-mbrace.cgi ;

But this gives me the following errors (this error does *not* occur
when I run bjam from the project root):

andrej_at_amd64:~/mbrace/trunk/cgi$ bjam

When I replace INSTALL_PATH in the install command like this:

install /root/htbin : nph-mbrace.cgi ;

Then it works perfectly fine...

Hmmm....

Cheers,
