The current origin/master is not building for me:

qemu-img.o: In function `add_format_to_seq':
/bghome/tmusta/powerisa/qemu/qemu/qemu-img.c:73: undefined reference to `g_sequence_lookup'

    qemu-img: sort block formats in help message

    The help message for qemu-img lists the supported block formats, of
    which there are 27 as of version 2.0.50. The formats are printed in
    the order of their driver's position in a linked list, which appears
    random. This patch prints the formats in sorted order, making it
    easier to read and to find a specific format in the list.

    [Added suggestions from Fam Zheng <famz@redhat.com> to declare variables
    at the top of the scope in help() and to omit explicit cast for void*
    opaque.

It appears that this code is dependent on glib.h function that is newer than one of my build systems
(RHEL 6 update 5, gcc version 4.4.7 20120313 (Red Hat 4.4.7-4))

Is this a known limitation?  i.e. is QEMU 2.1 going to prereq a newer version of glib2?
