And the --enable-pc-files support in ncurses is completely stupid:

 (*) In its configure.in file, it checks whether the PKG_CONFIG_LIBDIR
     directory exists to decide whether it should install .pc files or
     not. This is stupid, it should just install them unconditionally
     (you already said --enable-pc-files, so why bothering checking
     once again?). But anyway, you pass
     PKG_CONFIG_LIBDIR=/home/foo/mybuildsystem/staging/usr/lib/pkgconfig,
     and there you go, ./configure understands that you *REALLY* want
     those damn .pc files to be installed.

 (*) But then, their misc/Makefile.in installs the .pc files not in
     $(PKG_CONFIG_LIBDIR), but in $(DESTDIR)/$(PKG_CONFIG_LIBDIR). So,
     since your DESTDIR is going to be /home/foo/mybuildsystem/staging,
     and PKG_CONFIG_LIBDIR
     is /home/foo/mybuildsystem/staging/usr/lib/pkgconfig, guess what
     happens... your .pc files are installed
     in 
/home/foo/mybuildsystem/staging//home/foo/mybuildsystem/staging/usr/lib/pkgconfig.

And, to make things even better, their configure.in can't be parsed by
the normal autoconf, it needs a special fork of autoconf 2.13 to
regenerate the configure script, so you have basically no chance of
fixing things properly.

Sigh.
