Ghostscript project prefers to link against locally included libraries, but for most of those libraries offers a switch in the form of an environment variable set with configure, to instead link against system shared library. One exception for this mechanism is libtrio which is only offered to be linked from the local copy. Please support linking against system shared libtrio.
Fixed in: http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=fc0420d7 NOTE!!!: If the libtrio builds are ever changed to be influenced by the current locale, this change will be removed - the point of using trio is to avoid the glibc's stupid implementation of sprintf() and floating point numbers, where depending on the locale, the decimal point might be "." or "," - Postscript and PDF mandate "." for the decimal point.
