xmlsec1

I have been trying to get this module to work, but not succeeded. This is wrong forum, because my problem is not in this module but in xmlsec1 configuration in my server, but I hope you can gime some advice what to do.

Command "/usr/local/bin/xmlsec1 sign --privkey-pem /var/www/sec-keys/dsaprivkey.pem --pubkey-der /var/www/sec-keys/dsapubkey.der --output /var/tmp/SIGNED_xxxxxx /var/tmp/TO_SIGN_xxxxxx" causes this kind of error message:

Error: keys manager creation failed

System is Fedora Core 4 and I have installed libxml2, libxslt and openssl. And the keys were created exactly by the instructions in Google's help page.
