Hello. I am unable to build bahamut-2.1.4 from source if I pass --disable-openssl to configure.  It configures, but fails on the make phase. I am using irc for a ham radio project that does not require ssl. Builds with ssl enabled work fine with some of the same compiler warnings, but does not build with it disabled. The output is below. Thank you.
