Recurrent Problems on Leopard

environment variables become blank

This manifests as error messages similar to the following.

unable to execute -DNDEBUG: No such file or directory

($CC is an empty string, so what was meant to be the the first argument to the compiler is now the first thing on the command line, and is treated as a command name by the shell.)

This issue is resolved in ​MacPorts 1.7.0.

ld: cycle in dylib re-exports with /usr/X11/lib/libGL.dylib

This is the result of a misfeature in XCode 3.0.0's linker; see Apple ​Technical Q&A QA1567. This can be fixed by upgrading to the latest ​Xcode Tools release.

macfuse fails to build

On versions of Leopard prior to 10.5.5, macfuse fails to build with the following error message (#15889).

undefined local variable or method `trans' for <UNDEFINED> ... </>:REXML::Document

Updating to 10.5.5 or later using Software Update should resolve this issue.

/usr/X11/lib/libXrandr.2.0.0.dylib: No such file or directory

This is a problem encountered when trying to install gtk2 on some Leopard machines (#14592, #17008, #17356). The .la files in /usr/X11/lib refer to the wrong library. You may also see this problem with other X libraries such as libXdamage.

Upgrading to the latest ​Xquartz release should fix this problem.
