An "undefined symbol" indicates the use of a bad (older?) lib.

Found indeed something confusing in our 0.9.8.5 version, which installs
into "/usr" instead of the usual "/usr/local". Because you did an "rpm -U",
you most probably upgraded from an previous version installed in "/usr/local". 

In that case and depending on you path settings you run the exe from 
"/usr/local/bin" using the "/usr" libs or vice versa, no?

	$> which medcon
	$> ldd /path/to/medcon

Sorry for that mess. But here is a way to clean it up: you can do an 
install/uninstall from a source package (in case you don't have that older RPM)

$> ./configure --prefix=/usr/local
$> make
#> make install
#> make uninstall

So, made all that sense?
