Here is a fairly similar post:
http://r.789695.n4.nabble.com/Build-from-Source-fails-on-Loading-required-package-Matrix-td4640371.html

The eventual "solution" of that thread seems to be building from tar ball, which is quite beside the whole point of building from svn trunk.

FWIW, it is very unproductive to talk about "bad practice" - in a hand-waving undocumented/unsubstantiated manner - and options that might or might not work. If "--enable-lto" (or any other options, or build within the dev directory) does not work reliably, it should be either disabled/removed, or documented, or both. Anyway, it has not been working for over 4 months.

You have about 6 weeks before this becomes a big problem - "big" as in "wide-spread".
