The following patch allows building the lvm utilities in a 
seperate directory from the source.  It is a patch agains 1.0.1rc1
and has been tested with linux 2.2.18.

 If you are not familiar with patching or building the kernel then
 consider looking for pre-built binaries of LVM.
 
-Configuring LVM for your kernel
--------------------------------
-
-You can skip this step if you are sure you ran configure with the correct
-options.
-
-o untar your clean Linux kernel
-
-o run 'make distclean' in the directory above this one to clean up any
-  previous configure information.  If you get an error that says
-  "make: *** No rule to make target `distclean'.  Stop." it generally
-  means your source tree is clean and you can ignore it.
-  
-o run configure in the directory above this one to produce 'Makefile', making
-  sure to specify the '--with-kernel_dir=' flag if your kernel source is not
-  in '/usr/src/linux'.
-
 Creating the patch
 ------------------
 
-o check the following variables at the top of 'Makefile' in the PATCHES
-  directory
+o Check the following variables at the top of 'Makefile' in the PATCHES
+  subdirectory of your lvm build directory.  If these are not correct
+  then you probably didn't pass the correct values to configure.
 
   KERNEL_DIR should point to the kernel source that you wish to patch
   eg, KERNEL_DIR=/usr/src/linux
 
   LVM_VERSION the LVM version
-  eg, LVM_VERSION=0.9.1_beta5
+  eg, LVM_VERSION=1.0.1
 
   KERNEL_VERSION the version of your kernel that is to be patched
   eg, KERNEL_VERSION=2.2.18
