Hello,
I tried to use it on my VL 5.8 SOHO Final and I got the following message when started from the terminal.
./wengophone.sh
(info) 14:56:10 Wenbox::Wenbox(): Wenbox dll not loaded
qtwengophone: cannot connect to X server
When I started it from Konqueror (as root) it opened nicely

I created Link to application on my desktop and it started up OK, , I registered as Wengophone user.
Now, tet\sting with use, any bugs...

please report bugs on
www.openwengo.org or on IRC chanell #openwengo on irc.freenode.net
I archived openwengo binary file with added libstdc++ and you can download it from
http://www.gnulinuxcentar.org/WengoPhone-2.1-minsizerel.tar.gzUntar it , create a link to application on your desktop pointing to openwengo.sh in folder of openwengo and it should start and work.
If for some reason you miss or delete libstdc++ from your openwengo folder you can use them packed in .tar.gz archive that you can download from
http://www.gnulinuxcentar.org/Archive.tar.gzUntar archive and copy those files to your openwengo folder and start openwengo.sh from your GUI.
Thanks,
Vedran
