This is suspicious Can't open perl script "INSTALLDIRS=site" INSTALLDIRS=site is an argument for Makefile.PL, not perl

You should break out of CPAN, I think 

CPAN> look libapreq2

[download]
or with cpanplus 
cpanp z libapreq2

[download]
and run 
perl Makefile.PL
make
make test
make install

[download]
manually
