| and other tools. I expect, e.g., that if
| ./configure
| works that also
| ./configure --prefix=$HOME
| will work and that the same libraries are linked in.

| I understand the reported pain, but the suggested fix, I think, might

Are you worried about people being confused why configure with
--prefix=$HOME works, but not without or something else?  My first worry
was «what happens when you have multiple .pc files with the same name»,
since that's a situation which we don't deal with too well today and
starting to mangle the search path would make this into a more common
situation causing confusion.
