Hi, I am trying to build Qwt 6.1.0 RC3 on OS X doing the following:

Qt Code: 
  1. $ cd qwt-6.1-rc3
  2. $ qmake
  3. $ make
To copy to clipboard, switch view to plain text mode 

but then, I got the following errors/warnings:

...

Regarding the two warnings, it would probably be nice to fix them, especially the second one. As for the error, I would have expected Qwt's build system to handle it? If not, what is then needed to get Qwt to build out-of-the-box on OS X?
