[Paraview] Qt library install question

[Dan Lussier]

Here is the result:

% otool -L /opt/local/libexec/qt4-mac/lib/QtGui.framework/Versions/4/QtGui

/opt/local/libexec/qt4-mac/lib/QtGui.framework/Versions/4/QtGui:
	/opt/local/libexec/qt4-mac/lib/QtGui.framework/Versions/4/QtGui
(compatibility version 4.6.0, current version 4.6.3)
	/opt/local/libexec/qt4-mac/lib/QtCore.framework/Versions/4/QtCore
(compatibility version 4.6.0, current version 4.6.3)
	/System/Library/Frameworks/Carbon.framework/Versions/A/Carbon
(compatibility version 2.0.0, current version 152.0.0)
	/opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current
version 1.2.5)
	/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit
(compatibility version 45.0.0, current version 1038.29.0)
	/opt/local/lib/libpng12.0.dylib (compatibility version 45.0.0,
current version 45.0.0)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current
version 103.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 125.0.1)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 227.0.0)
	/System/Library/Frameworks/CoreServices.framework/Versions/A/CoreServices

(compatibility version 150.0.0, current version 550.19.0)
	/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices
(compatibility version 1.0.0, current version 38.0.0)
	/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation
(compatibility version 300.0.0, current version 751.21.0)

This Qt library (in /opt) is from MacPorts, while I built the other
one (/Code/qt-pv/...) from source.  I used the one built from source
for building PV.  Here is the same otool command against that library:

% otool -L ~/Code/qt-pv/lib/QtGui.framework/Versions/4/QtGui
/Users/<user-id>/Code/qt-pv/lib/QtGui.framework/Versions/4/QtGui:
	/Users/<user-id>/Code/qt-pv/lib/QtGui.framework/Versions/4/QtGui
(compatibility version 4.6.0, current version 4.6.3)
	/Users/<user-id>/Code/qt-pv/lib/QtCore.framework/Versions/4/QtCore
(compatibility version 4.6.0, current version 4.6.3)

(compatibility version 2.0.0, current version 152.0.0)
	/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3)
	/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit

Thanks.
