The Carp routines are useful in your own modules because they act like die() or warn(), but with a message which is more likely to be useful to a user of your module. In the case of cluck, confess, and longmess that context is a summary of every call in the call-stack. For a shorter message you can use carp or croak which report the error as being from where your module was called. There is no guarantee that that is where the error was, but it is a good educated guess.
This module can build the C portions of Perl modules by invoking the appropriate compilers and linkers in a cross-platform manner. It was motivated by the 'Module::Build' project, but may be useful for other purposes as well. However, it is _not_ intended as a general cross-platform interface to all your C building needs. That would have been a much more ambitious goal!
Configure-time utilities for using C headers, libraries, or OS features
Often Perl modules are written to wrap functionality found in existing C headers, libraries, or to use OS-specific features. It is useful in the Build.PL or Makefile.PL file to check for the existance of these requirements before attempting to actually build the module.
