Summary: Failed to load libGL: dlopen(libGL.1.dylib, 266): image
                    not found
           Product: Wine
           Version: 1.1.5
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: build-env
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

After upgrading XQuartz to latest version 2.3.1 and installing wine 1.1.5 using
macports (wine-devel port) got following:
--
err:wgl:has_opengl Failed to load libGL: dlopen(libGL.1.dylib, 266): image not
found
err:wgl:has_opengl OpenGL support is disabled.

If set LD_LIBRARY_PATH to /usr/X11/lib then libGL works but faced to:
---
err:wgl:has_opengl  glx_version is 1.2 and GLX_SGIX_fbconfig extension is
unsupported. Expect problems.

Could you explain why it is necessary to set env variables after installation?
Is it wine compilation defect?

Thanks in advance,
Vladimir
