thanks.

so¹ it seems that there are two (unrelated) problems:
- - the "-std=c++11" flags are not passed on to the submodules (libs/pbd
& libs/midi++)
- - sooperlooper assumes some incompatible version of sigc++-2.0

(2) is not that hard to fix; just replace in a number of files:
- -#include <sigc++/object.h>
+#include <sigc++/trackable.h>
(it seems that with sigc++-2.5.2 the object.h file was removed; thus a
proper fix would check for the existence of object.h vs trackable.h
and include the existing one)

(1) i found harder to fix. it seems that the configure scripts for
both midi++ and pbd overwrite the CXXFLAGS variable.
i haven't found a way yet to add build-flags to those without patching
the sources.


i think that both issues should be reported upstream and fixed (in any
order)

¹ admittedly i did fetch the sooperlooper source package and tried to
build it myself, in order to come to these conclusions; rather than
see all this from the cryptic error you got :-)
