    pkg: use exact same error message as pkg-config when dependency is unresolvable

  • pkgconf - compiler and linker configuration for development frameworks
    ----------------------------------------------------------------------
    
    1. General summary.
    
    pkgconf is a program which helps to configure compiler and linker flags for
    development frameworks.  It is similar to pkg-config, but was written from
    scratch in Summer of 2011 to replace pkg-config, which now needs itself to
    build itself (or you can set a bunch of environment variables, both are
    pretty ugly.)
    
    Implementations of pkg-config, such as pkgconf are typically used with the
    PKG_CHECK_MODULES autoconf macro.  As far as I (nenolod) know, pkgconf is
    compatible with all known variations of this macro.  However, I have not
    extensively tested yet for compatibility.  pkgconf detects at runtime
    whether or not it was started as 'pkg-config', and if so, attempts to set
    program options in a way where it's behaviour should be similar.
    
    In terms of the autoconf macro, it is possible to specify the PKG_CONFIG
    environment variable, so that you can test pkgconf without overwriting your
    pkg-config binary.  (hint: export PKG_CONFIG=/usr/bin/pkgconf)  However,
    if you do this, it will be running in native mode, so you may have some very
    strange results as the dependency graph is compiled differently in native
    mode.
    
    2. Technical design.
    
    pkgconf builds an acyclic directed dependency graph.  This allows for the user
    to more conservatively link their binaries -- which may be helpful in some 
    environments, such as when prelink(1) is being used.  As a result of building
    a directed dependency graph designed for the specific problem domain provided
    by the user, more accurate dependencies can be determined.  pkg-config, on the
    other hand builds a database of all known pkg-config files on the system before
    attempting to resolve dependencies, which is a considerably slower and less
    efficient design.
    
    pkgconf also does not provide support for pointlessly stupid features implemented
    in pkg-config.  If you think a feature is not dumb, then you should file an
    'Improvement' task on Atheme's JIRA instance at <http://jira.atheme.org>.
    
    3. Compiling.
    
    pkgconf is basically compiled the same way any other Atheme project is compiled:
    
       $ ./configure
       $ make
       $ sudo make install
