Building on Mac OS X 10.7

FYI, attached BUILD-lo script allowed me to build recent LO master on 
Mac OS X 10.7 with Xcode 4.  A few comments:

* It builds into ~/Software/lo (which must not yet exist).

* It uses MacPorts for the various dependencies, but in a way that does 
not pollute the machine (by checking out and building a MacPorts 
installation completely local to the LO build).

* The pkgconfig and libidl stuff, and maybe also the grep stuff, is 
probably only needed for moz (at least, that's the first module where I 
encounter need for it).

* Instead of symlinking doxygen into ~/Software/lo/bin, it could also be 
included in autogen.lastrun via --with-doxygen=... if it were clarified 
how to escape content in autogen.lastrun (newlines in HOME, anyone?). 
(This would of course be avoided if the script would pass the 
configuration arguments to an explicit call of autogen.sh.)

* --with-macosx-version-min-required=10.6 (instead of 10.7) is needed at 
least for the moz and python modules.

* As per SUS an unset or null PATH means implementation-defined 
behaviour (that cannot easily be added to with PATH=${PATH}:...), the 
script simply fails on an unset or null PATH.
