GPL Compliance
You are currently linking against libraries that link against GPL-incompatible code (namely, OpenSSL). Unfortunately this is against the terms of the GPL licence that Pidgin and libpurple is licensed under, as Pidgin/libpurple does not have a license exception for OpenSSL.
You will need to change the libraries you are using in order to comply with the GPL, or else cease distributing compiled copies of this plugin.
ok, I will start to solve this problem.
Easiest way to solve this "bug" is to do as @EionRobb said and just stop distributing binaries. You can still distribute the code and have users compile their own binaries.
@leggewie not sure who you're quoting but no-one said "bug":)
This is a legal issue that needs to be resolved though
"or else cease distributing compiled copies of this plugin"
