I always add a second FINDLIBS in my local boost to make things work 
because indeed in many cases this is necessary. Vladimir however told me 
that there is better dependency control in v2 and thus such ugly 
workarounds should not be necessary anymore.

But the lexicographical sort was a new thing which really messes things 
up. Theoretically this 'random' order of libraries in the link-line 
obliges you to add FINDLIBS n times to the link-line, where n is the 
total number of libraries.
