Linux Compatibility

[Girish L]

Hi

 I have a freeBSD 5.2-CURRENT version running on a intel dual processor machine.

I need to turn the LINUX COMPATBILITY ON, but unfortunately the source
code for this version is not on the system.

If I do a sysinstall to obtain the source code, the system fails to
find the matching version and if i set the option to "any" release or
download any other version
(say 5.2.1-RELEASE) and modfiy the Kernel Configuration file GENERIC 
to add the option COMPAT_LINUX, I get a error on running config(8).

this error points about a version mismatch

Can anyone point me to the source code for 5.2-CURRENT release
or help me add the linux compatibility option and turn the linux
compatibility ON.

Thanks for any help in this regard
