+Subject: [PATCH] Replace lv2core by lv2
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When building lv2 from git, triceratops fails because it cannot find lv2 any
+more.
+
+Reason: lv2core.pc was removed in lv2 [1].
+
+Using lv2.pc works perfectly fine - the contents of both files in lv2 version
+1.14 are similar from pkg-config point of view.
