>Description:
I found that on my system certain Virtualbox kernel modules fail to load after they are build from ports system as opposed to ones  installed from packages. For instance, I decided to upgrade virtualbox-3.2.6 to virtualbox-3.2.8. THe former was from packages, the new version was build from ports with portupgrade.

But when I try to load new modules I am unsuccessfull: 
# kldload vboxdrv // this works OK

#kldload vboxnetflt // returns "No such file or directory"

Additionally I get "link_elf: symbol RTR0Init undefined" on 1st console and in dmesg.

Yesterday I csup'ped to the latest stable sources, rebuilt the kernel and rebuilt Virtualbox (3.2.10) - no luck, still the same issue.

Apparently something is not built up correctly.

I have the following make.conf:

# added by use.perl 2010-07-30 23:49:23
PERL_VERSION=5.10.1

#CFLAGS= -O2 -fno-strict-aliasing -pipe

CFLAGS = -pipe

# Seems to broke some kernel modules
#COPTFLAGS= -O -pipe
-------------------------------------
I also noted that certain other ports that require kernel modules (e.g. cuse4bsd and webcamd) fail to load the module and work if they are built from sources not acquired from packages.

>How-To-Repeat:
1. Install virtualbox-ose-kmod from sources
2. Try to load vboxnetflt with kldload
3. See the dmesg message and no module is loaded
>Fix:
Using packages, even from older version with more new main port, works.
