If I just want to use it in wine builtin IE, what steps should I follow ? It seems that winerootcerts.exe should help, but I can't find it on the web.
It depends on your distro. Wine searches for trusted root certificates in the following locations:
/etc/ssl/certs/ca-certificates.crt /etc/ssl/certs /etc/pki/tls/certs/ca-bundle.crt /usr/local/share/certs/
The first location is used by Debian/Ubuntu, for example, while the third location is used by RedHat/Fedora. You'll want to ask in your distro support channel how to install one.
