I want to change the POSTOP macro definition in the generated makefile. How do I do it? According to the ExtUtils::MM_Unix source code, the value of POSTOP can be changed by providing an argument to the dist() function. However, the function Module::Install::Makefile::write() does NOT allow anything to get passed in to the dist() function -- nothing except its own hardcoded PREOP value, that is. 8-(
