# nginx does not utilize a standard configure script.  It has its own
# and the standard configure options cause the nginx configure script
# to error out.  This is is also the reason for the DESTDIR environment
# variable.  The configure script(s) have been patched (Patch1 and
# Patch2) in order to support installing into a build environment.
