Subject: Add PROJ.4 version check to ensure that a minimum version of 4.5.0 is installed.... 
X-Git-Tag: 1.4.0b1~818

Add PROJ.4 version check to ensure that a minimum version of 4.5.0 is installed. This is to ensure that the pj_set_searchpath() function is present (note: it was actually added in 4.4.9, however we version detect on major.minor rather than major.minor.release)
