Virtuozzo 4.6 does not create VE 1 at installation time

Problem:
After installing the latest Virtuozzo Software (V 4.6) there is no VE 1 and the hardware node cannot be accessed by PMC or similiar tools.


Solution:

From V4.6 on you need to install PVA (Parallels Virtual Automation) additonally for having a VE1.
So you first install Virtuozzo:

./vzinstall-linux-i386.bin install

Then you need to supply a valid license:

echo "BLABLA-YOUR-LICENSE" | vzlicload -i

Finally you can try to install PVA:

./pva-setup-deploy.x86_64

which gave following error:

Dependency check failed:
libapr-1.so.0()(64bit) is needed by httpd-2.2.3-6.el5.centos.1.x86_64
libaprutil-1.so.0()(64bit) is needed by httpd-2.2.3-6.el5.centos.1.x86_64

(I am running OS Centos 5.6)
Tried my luck with

yum install httpd

and again with

./pva-setup-deploy.x86_64 install

and this time everything went smoothly.
