You have a couple of choices ...
1. Download the source to the Samba 3.6.3 package you have installed
(perhaps on your distro) and build it and then build your module as a
out-of-tree module (using the instructions on the Wiki). However, if
you coded your module to the 4.1.x standard, you will likely have to
change things since the VFS interface has changed quite a bit since
3.6.x.
2. Deinstall Samba 3.6.3 and use make install on the source you built,
however it will be in different places than the package you installed
placed them and the options selected will likely not be the same as
the package had,
3. Find a 4.1.x package for your distro and download the source
package and build that and then add your module and build and create
packages and add that package.
Not a good set of choices, I am afraid because there are alligators all
around.
