#66096: libevent @2.12.12_1: Fails when libressl @3.6.0 installed, due to
BIO_get_init
-------------------------+--------------------------------
 Reporter:  daphnediane  |      Owner:  jerryyhom@…
     Type:  defect       |     Status:  assigned
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.8.0
 Keywords:  haspatch     |       Port:  libevent, libressl
-------------------------+--------------------------------
 libevent fails to build with newer versions of libressl. Cause is related
 to BIO_get_init() becoming an opaque interface in 3.5+.

 The attached patch file based on this upstream commit:
 https://github.com/libevent/libevent/pull/1227/commits/883630f76cbf512003b81de25cd96cb75c6cf0f9
 fixes the problem.
