IAM 10.1.4 on Ubuntu

Starting off with a OID Repository, with is of the "Wrong Version" (Installed with REPCA 10.1.4 - trying to install 10.1.4...), now several wizards fail.

It starts with the Delegated Administration Service Configuration Wizard; Apache fails to start with:

Syntax error on line 1113 of /oracle/iam/Apache/Apache/conf/httpd.conf:
Cannot load /oracle/iam/Apache/Apache/libexec/mod_rewrite.so into server: /oracle/iam/Apache/Apache/libexec/mod_rewrite.so: undefined symbol: dbm_fetch

and several others.
In spite of earlier actions, one needs to:

sudo apt-get install libdb1-compat

That still does not resolve everything - but at least I can use LDAP.
