dovecot - Jun 2016 - SSL Problem with -git master-2.2 tip (24 June 16)

Current master-2.2 branch of Dovecot compiles for me on Gentoo x86_64 
but experiences symbol errors when starting up:

Jun 24 08:38:00 thunderstorm dovecot: lmtp(8180): Fatal: Couldn't load 
required plugin /usr/lib64/dovecot/libssl_iostream_openssl.so: dlopen() 
failed: /usr/lib64/dovecot/libssl_iostream_openssl.so: undefined symbol: 
SSL_COMP_free_compression_methods
Jun 24 08:38:00 thunderstorm dovecot: master: Error: service(lmtp): 
command startup failed, throttling for 16 secs

I suspect that this is because I have libressl installed on my systems 
instead of OpenSSL.

A known commit point which does not work is:

f5e6b05684328b9800ccd973c73027300c832d65

However a few commits earlier this problem does not occur:

f292589f4b85e02d97d974dfe34324c6c0bb9d9f

Looks like commit bff052bd29dbf7175ee6cd14bd14bcea1900b869 : 
"lib-dcrypt, lib-ssl-iostream: Share OpenSSL init/deinit code." may
have
broken the tree for LibreSSL/non OpenSSL users.

Thanks.  Better but perhaps not quite right yet - I'm now seeing lots of 
these messages logged:

Jun 30 08:07:22 thunderstorm.reub.net dovecot: doveadm: Warning: 
CRYPTO_set_mem_functions() was called too late
