openbsd 3.6 installation from stable source (0.1.0.15)

[poncenby smythe]

dear list,

i first installed libevent 1.1a using:
./configure --prefix=/thisdir
make
sudo make install

no errors occured.

i then installed tor using:

./configure --includedir=/thisdir/include --libdir=/thisdir/lib
make
sudo make install

no errors occured.

then when executing tor it complains that i am using an old version  
of libevent and tor will be buggy.

I think the problem is that I have never really understood how to  
compile source packages with certain libraries/includes that are not  
in standard paths.

apologies for such a newbie question.
