[collectd] Compiling 5.0 on Ubuntu 11.04 still failed

[Amer]

Hello.

Did anyone successfully compile collectd 5.0 source on Ubuntu 11.04? I
can't compiled the source without getting these errors which then
halted the compiling process half way through

Making all in owniptc
make[3]: Entering directory `/root/collectd/src/owniptc'
/bin/bash ../../libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H

I saw someone bring up the same issue before here
http://mailman.verplant.org/pipermail/collectd/2011-May/004500.html
and it was suggested to use the fresh source pulled directly from your
git. I've given that a go but unfortunately it still fail to compile
with same error.

Any idea?
