I have the same compile flags, however I opted for the hcache backend as tokyocabinet. Even with GDBM, I could not implement header caching on mbox :( In fact I thought at one time it was working with mbox as the loading was apparently faster than without the header_cache set in config. But I could not reproduce it.
So is this indeed supported for mbox? It works for me consistantly with imap and with maildir. Faster and the files in the header_cache dir are uopdated. Nope on both counts with mbox. What is the reason for this? Eric ~ % mutt -v Mutt 1.5.23 (2014-03-12) Copyright (C) 1996-2009 Michael R. Elkins and others. Mutt comes with ABSOLUTELY NO WARRANTY; for details type `mutt -vv'.
