Subject: MacOS 10.11 (El Capitan) openssl compilation errors  
I recently upgraded my macbook to MacOS 10.11.  The compilation of MIDAS failed after the upgrade, 
complaining about  

gcc  -c -g -O2 -Wall <snip> src/mongoose.c
src/mongoose.c:322:10: fatal error: 'openssl/ssl.h' file not found

It seems that MacOS has now fully removed openssl header files (they were deprecated for a while).  There 
seems to be some notes on that here

Konstantin suggested installing open-source builds of openssl using MacPorts.  I did that and MIDAS 
compiled fine.  I documented the procedure here:
