[oe] Showing build dependencies, boost needs libxt?

[John Faith]

Hi,
I'm trying to build boost_1.40 for omap3530.  When I use 'bitbake -g 
boost' I see no libxt or X11 stuff in the generated .dot files, but when 
I 'bitbake -c compile boost' it first tries to build libxt which fails 
for me (missing headers, which is another problem).  I'd like to 
understand where the dependency on libxt is.  Is there an easy way to 
get this info from bitbake?

Thanks,
John
