dkms "--kernelsourcedir" option not work

[shockwave]

Hi, my os is lubuntu 13.04 x86_64
recently i need to use dkms to rebuild a module, so i do :
dkms build -m (module name) -v (version)
but it say it can't find linux-headers of my kernel version, i felt strange because it has already put in /usr/src
so i give the "--kernelsourcedir" option :
dkms build -m (module name) -v (version) --kernelsourcedir (/usr/src/my-kernel-headers)
but it still didn't work!!
i've tried :
dkms build -m (module name) -v (version) --kernelsourcedir (/usr/src/)
and
dkms build -m (module name) -v (version) --kernelsourcedir=(/usr/src/my-kernel-headers)
also
dkms build -m (module name) -v (version) --kernelsourcedir=(/usr/src/)
but the error message still said that it can't find the headers

although in the last i found that the problem is that in my /lib/modules/(kernel-version)/
the "build" symlink was broken, and /lib/modules/(kernel-version)/ is the default path of dkms

But why the --kernelsourcedir didn't work?
