>Description:

When you build an plugin for nodejs with node-waf, and give different
directory for source and build, it maybe fault.  node-waf would
compute a relative path from build directory to source directory.  It
works if no symbolic link in the absolute path of build directory.
But, it is fault when a symbolic link in the absolute path.  For
example, for most FreeBSD user, their home directory is in
/usr/home/XXXX.  But, there is a symbolic link /home to /usr/home.  If
your home is specified with /home/XXXX and another path is /usr/OOOO,
node-waf will get a relative path from /home/XXXX to /usr/OOOO as
../../usr/OOOO.  It suppose /home/XXXX/../../ is root directory, but
it is actually /usr.  So, absolute path of relative path
../../usr/OOOO in /home/XXXX is actually /usr/usr/OOOO, it is
different from the expected one; /usr/OOOO.
