Module::Install::External - Specify dependencies on external non-Perl things "Module::Install::External" provides command that allow you to declaratively specify a dependency on a program or system that is not Perl. The commands it provides are similar to those in Module::Install::Can, except that they implement an explicit dependency, in addition to just working out if the particular thing is available.

requires_external_cc
requires_external_cc; The "requires_external_cc" command explicitly specifies that a C compiler is required in order to build (at make-time) the distribution. It does not take any params, and aborts the Makefile.PL execution in a way that an automated installation or testing system will interpret as a "NA" ("not applicable to this platform") result. This maybe be changed to an alternative abort result at a later time. Returns true as a convenience.

requires_external_bin
requires_external_bin 'cvs'; The "requires_external_bin" command takes the name of a system command or program, similar to the "can_run" command, except that "requires_external_bin" checks in a way that is a declarative explicit dependency. The takes a single param of the command/program name, and aborts the "Makefile.PL" execution in a way that an automated installation or testing system will interpret as a "NA" ("not applicable to this platform") result. Returns true as a convenience. Work out how to save the external dependency metadata, in agreement with the larger Perl community. Implement the agreed external dependency metadata solution.
