I loaded source code from repository, did some debugging and installing necessary packages
at a point the configure script asks for cbindgen for rust with minimum version 0.27.0 , which is part of excalibur and cannot be backported.

grep -isr cbindgen build/moz.configure/bindgen.configure | grep -i version 
def check_cbindgen_version(cbindgen, fatal=False):
    cbindgen_min_version = Version("0.27.0")
    version = Version(check_cmd_output(cbindgen, "--version").strip().split(" ")[1])
    log.debug("%s has version %s" % (cbindgen, version))
    if version >= cbindgen_min_version:
    cbindgen version {} is too old. At least version {} is required.
                version, cbindgen_min_version, cbindgen
        check_cbindgen_version(cbindgen_override[0], fatal=True)
        if check_cbindgen_version(candidate):
    check_cbindgen_version(candidates[0], fatal=True)

aptitude show cbindgen
Paket: cbindgen                                 
Version: 0.24.3-2+b2

How come : has a backport gone wrong ?
can I modify line 2 of grep output without harm ?
Is it a bug ?
