No. LDPATH (if I've got the name right) tells the system where to look for
libraries, not include files.

For the latter, you need something like either a link in /usr/include
named "X11" pointing to the right directory, or you need an
-I /some/directory/path/to/a/dir/which/contains/X11 
Note: your path should not end w/ X11. An ls of what youput above followed
by a "/" and then "X11/file" should find the file.

Take care,
