bonobo-activation error

[the jackol <jackol gmx net>]

Hello,

When doing a "make install" on bonobo-activation, I get the following
errors:

------------------------

activation-context-query-parser.o: In function `qexp_parse':
/root/garnome/garnome-0.10.1/gnome/bonobo-activation/work/bonobo-activation-0.9.9/server/./activation-context-query-parser.y:192: undefined reference to `initFlex'

make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive-am] Error 2
make: *** [build-work/bonobo-activation-0.9.9/Makefile] Error 2

------------------------

First time I got this error, I installed flex, reconfigured and tried
the make again, resulted in the same errors.

Any idea why this happens? What do I need to do to get over this?

TIA

Regards,
