+From: Lubomir Rintel <lkund...@v3.sk>
+
+APR shared objects were not properly linked when they were installed to a
+specific DESTDIR. This was broken in r733406, which attempted to fix
+rpaths for the obscure platforms that still use them.
+
+With this applied, we call apreq2-config we just installed and add a library
+path of libraries in DESTDIR to linker.
