 The 'configure' script is generated by the autotools from the
 'configure.in' file.  So modifying the 'configure.in' file require you
 to run all the autotools chain to regenerate the 'configure' script
 before continuing.  This is the reason you had to run 'autogen.sh'.
 
 When the mono folks release a new mono tarball, they include the generated
 'configure' script in it so we have to either patch 'configure.in' and re-r=
 un
 the whole autotools chain, or patch the generated 'configure' which avoids =
 us
 all the mess that commes with the autotools if we have to change something
 there.

 I get:

 which is what you are expecting, right ?  Then I guess I can commit this
 change.
