 Hi,

 The attached Portfile adds a qwt61 variant (replacing the qwt-devel
 variant that installs an outdated release 6.1 release candidate), which
 installs the current Qwt 6.1.2

 The following changes are necessary:
 - Update Portfile according to attached patch
 - Remove: files/patch-designer_designer.pro.610rc3.diff  files/patch-
 qwtbuild.pri.610rc3.diff  files/patch-qwtconfig.pri.610rc3.diff  files
 /patch-qwtfunctions.pri.610rc3.diff
 - Add attached: files/patch-designer_designer.pro.61.diff  files/patch-
 qwtbuild.pri.61.diff  files/patch-qwtconfig.pri.61.diff

 A few comments:
 - When trying to update patch-qwtfunctions.pri.61.diff from the old
 release candidate build, linking failed. Omitting the patch seems to do
 the right thing.
 - I am not sure if I need to add something to ensure that existing
 installations of qwt-devel get upgraded to qwt61.
 - If I am not mistaken, the variants "debug" and "examples" do not do
 anything and could be removed.
