I do.  This is why I started this thread.

I was thinking built-time dependencies.  What is required by a package 
to successfully configue, make and make install.  I would think that 
run-time dependencies would very similar (actualy a sub-set) of the 
build-time ones.  This may not be true in all cases, but probably true 
in most.  This is what configure scripts are for in the first place - to 
make sure that the environment has all the required stuff before running

I agree.  That seems a bit scary.  Has anyone seen this directly?  I 
have only been doing LFS for about 9 months.  In that time I have built 
about 12 boxes. I like to look at the configure logs on each build to 
see what was found and not.  Have learned a lot by doing this.  I have 
not seen an instance where confire said it could not find something and 
make and/or make install kept on going.  Actually, in my experience, 
configure crapped out when it could not find something important that 
the program needed.

I would think so.  There are a lot of folks on these lists with some 
excellent experience.

Remember that my origianl goal was to try and find and easier way to 
find a package's dependencies without going through a manual inspection 
of the files and/or do a "Gerard" style manual build.
