thanks for the input jim.  i dunno about switching all my libs though ;-(  =
the
age thing is really handy so that applications can say "give me the more
recent version that supports my interface" and end up getting v17.2.16 even=

the initial application was built against v3.2.2.  on the other hand there =
is
no ruby 'linker' other than require_gem so maybe i ought to convert...

cheers.
