Further digging showed that vigra is built with corresponding -Wl,-rpath=/usr/local/lib/gcc46 which makes it use correct libstdc++. However, that rpath is removed by cmake on installation: -- Installing: /usr/local/lib/libvigraimpex.so.4.190 -- Installing: /usr/local/lib/libvigraimpex.so.4 -- Installing: /usr/local/lib/libvigraimpex.so -- Removed runtime path from "/usr/local/lib/libvigraimpex.so.4.190" I have a fix for that: http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/176901 With it, no LD_LIBRARY_PATH will be needed, but USE_GCC=4.6+ will still be required for ALL ports which depend on graphics/vigra as long as it has USE_GCC=4.6+ itself. -- Dmitry Marakasov . 55B5 0596 FF1E 8D84 5F56 9510 D35A 80DD F9D2 F77D amdmi3@amdmi3.ru ..: jabber: amdmi3@jabber.ru http://www.amdmi3.ru
