Actually, that *is* rather surprising. The logical place would be to  
have them in ${prefix}/Applications, just like the frameworks were  
changed to use ${prefix}/Library (rather than /Library). But it was  
something hardcoded in the OS that made the subdirectory / 
Applications/MacPorts a better default... (and no idea why it  
couldn't just be a symlink)

It would be better/easier to have everything under ${prefix}, instead  
of installed into 4 possibly different locations (prefix, tclpackage,  
applications, frameworks). Ignoring system ports that actually need  
to install things elsewhere, that is (startup scripts, kernel  
modules, etc). That way, you would only have one toplevel folder to  
deal with...
