The reason was the absence of path to zope.viewlet egg from the 
sys.path. This slippage can surely be attributed to buildout. Also 
discovered that  out of 170 eggs listed in buildout.cfg only about 60 
appear in the scipts generated by buildout (paster, debug, ctl, python).
Does it sound reasonable to say that buildout machinary may need attention?
I do not know if this issue has hit others.
I added the paths to the scripts and moved one step further before 
getting caught in another situation. Now, the <browser:viewletManager> 
directive is absent. meta.zcml ???
