[cairo] Building on RedHat with non standard libary locations

[Bill Spitzak]

Despite indications that "./configure --prefix=x" will work to put  
everything in x, you must also set PKG_CONFIG_PATH to x/lib/pkgconfig  
and LD_LIBRARY_PATH to x/lib. Then do make install.

This is the #1 obstacle for programmers who want to work on Cairo on  
Linux. Apparently though there is some obscure reason why configure  
and the makefile cannot do this automatically, although I sure don't  
see it (--prefix changes where it reads the .h files, it makes no  
sense and is in fact dangerous for it to not change where it looks for  
the libraries to match!).

I also tried some other instructions that avoid the make install, but  
I was never able to get that to work.

One advantage is that the pkgconfig program works to produce the  
cflags and ldflags needed to make a program call your version of  
Cairo. Though seriously we should wonder why "-lcairo" by itself does  
not work...
