MacPorts does not use your PATH while building. It uses its own path  
setup, specifically to avoid problems that might be caused by other  
locations in your path.

The qucs configure script explicitly mentions /sw. We could attempt  
to patch the configure script to remove that reference. However, it  
is not supported to have both MacPorts and Fink installed at the same  
time, and you may run into similar issues with other ports. My  
recommendation is to remove Fink, or at least rename /sw to something  
else anytime you want to use MacPorts, because it can interfere like  
this.

Similarly, some software, including qucs, will look at /usr/local for  
dependencies. Therefore, it is unsupported to have anything in /usr/ 
local while using MacPorts.
