I'm the maintainer of wine in MacPorts, trying to figure out how to solve this problem (http://trac.macports.org/ticket/22293). Any help would be appreciated, including a reproduction recipe or a link to a Windows program I could install to see this error.

On my Snow Leopard 10.6.2 system with Xcode 3.2.1, it seems to find it; wine 1.1.33's configure says:


Code:
configure checking for GL/gl.h... yes
configure checking for GL/glx.h... yes
configure checking for GL/glu.h... yes
configure checking for up-to-date OpenGL version... yes

This is not necessary in MacPorts because /opt/local/bin/wine is actually a shell script with the following contents:


Code:
#!/bin/sh
# $Id$

DYLD_FALLBACK_LIBRARY_PATH="/opt/local/lib" \
"/opt/local/libexec/wine/wine" "$@"




The actual wine executable has been moved to /opt/local/libexec/wine/wine. The fallback library path used to also contain the system's X11 library directory (/usr/X11R6/lib on Tiger and older; /usr/X11/lib on Leopard and newer) but this was removed in r50572 (http://trac.macports.org/changeset/50572) because MacPorts now uses its own copy of X11, not the system's, for reasons explained in our FAQ (http://trac.macports.org/wiki/FAQ#syslibs).

The purpose of having a package management system like MacPorts is to encapsulate a recipe that will result in software being correctly installed on an operating system. (For MacPorts, the target OS is understandably Mac OS X.) It is more efficient for one person (the port maintainer -- me) to figure out how to configure and compile a program than for everyone to have to do it. Therefore I would prefer that we would amend the recipe until it works (please file bug reports (http://guide.macports.org/chunked/project.html#project.tickets) against ports that don't work) rather than throw it out entirely (building from source manually as you suggested).

This will have no effect in MacPorts because it deliberately clears the user's environment, to ensure a consistent experience.

The wine and wine-devel ports in MacPorts are hardwired to build for i386 only, even on Snow Leopard where the default is to build for x86_64. For this to work, all dependencies must either be built for i386 only as well, or built universal for i386 and x86_64. The latter is recommended, and accomplished by using the +universal variant. (universal_archs must also be set to "x86_64 i386" in /opt/local/etc/macports/macports.conf but this is the default on Snow Leopard.) If the user forgets to build dependencies universal, the wine ports detect this and suggest the user do this. If the user would rather build everything for i386 only, this can be done by setting build_arch to i386 in macports.conf.

MacPorts does not modify (or use) the system's X11; MacPorts shouldn't be modifying any part of Mac OS X, in fact; the whole point of MacPorts is to be self-contained. /usr/X11/bin/glxgears (which uses the system's X11 libraries) and /opt/local/bin/glxgears (which uses MacPorts') both work fine on my system.
