Random Software Advice

This is a disorganized collection of error messages I've encountered and how I fixed them. Hopefully they will pop up in Google searches on exact phrases from the error.

When installing ROOT 5.14 on OS X 10.5

ld: cycle in dylib re-exports with /usr/X11R6/lib/libGL.dylib
This error apparently is related to this problem which affects many X11 and OpenGL programs, not just ROOT. Apparently the solution is to invoke an otherwise-obscure flag to the ROOT "configure" command, telling it to use a different copy of libGL.dylib. ./configure macosx --with-opengl-libdir=/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/ (Double check your system: make sure libGL.dylib is actually in that frameworks directory.)
