invoke gb as module of big suite?

I'm planning to make browser engine.
gnome-basic is vb interpreter module in the suite.

what I expect to be best is:
	gathering script text from web page
	by filtering <script language="vb"> tag.
and give the script text to gb
to return result the script made.

but this moment is not the time yet.
I've gotta build fundamental page parsing system first,
and gb of cvs not finish compile for me, with error:
"""
../gb/.libs/libgb.al(gb-lex.lo): In function `parse_basic':
/home/Keizi/src/cvs/gb/gb/gb-lex.c:300: undefined reference to `gb_is_function'
collect2: ld returned 1 exit status
"""

btw, what I exactly want to know is this:
	gb is fit to module of big suite in this stage of development?
	or is that possible in the future?
