From 7ac852cd9709af98b6c12f2c7eca67915932e8a9 Mon Sep 17 00:00:00 2001 From: k-m_schindler Date: Sat, 22 Nov 2014 23:45:59 +0000 Subject: Fix PCRE on linux and macosx. The soname of libpcre.so is different depending on the system, e.g. .so.1 on Arch and .so.3 on Debian. Instead of always using libpcre.so.0, detect the soname for the current system.
