*** 
*** Configure failed - see above for the exact error message(s).
*** 
*** Most commonly, this is because the default PERL_CCFLAGS or PERL_OPTIMIZE
*** flags are not supported by your compiler. Less often, this is because
*** PERL_LIBS either contains a library not available on your system (such as
*** -lcrypt), or because it lacks a required library (e.g. -lsocket or -lnsl).
*** 
*** You can provide your own flags by creating a ~/.staticperlrc file with
*** variable assignments. For example (these are the actual values used):
