When building guile 2.0.11, configure fails with a "No package 'bdw-gc' found" error, and README claims that "bdw-gc" (confusingly referred to as "libgc") is still "available" at http://www.hpl.hp.com/personal/Hans_Boehm/gc/ . However, the garbage collector has long disappeared from HP's home page (at least since several years ago, definitely before 2014 when guile 2.0.11 was released).
The "bdw-gc" *appears* to be now located at https://github.com/ivmai/bdwgc . If this is the correct location the README should at least be updated. (The instructions should also at least be made consistent so that the gc is not called "bdw-gc" in one place and "libgc" in another.)
