I'm really confused. Some details might help. The report gives this:
PROGRAM OUTPUT
------------------------------
Output from '/usr/bin/make test':
perl Build.PL
Can't locate Module/Build.pm in @INC (you may need to install the
Module::Build module) (@INC contains: /etc/perl
/usr/local/lib/x86_64-linux-gnu/perl/5.22.1
/usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22
/usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22
/usr/share/perl/5.22 /usr/local/lib/site_perl
/usr/lib/x86_64-linux-gnu/perl-base .) at Build.PL line 6.
BEGIN failed--compilation aborted at Build.PL line 6.
GNUmakefile:101: recipe for target 'test-t' failed
make: *** [test-t] Error 2
That "perl Build.PL" is not coming from inside perl. It comes from
GNUmakefile picked up because this is GNU/Linux and /usr/bin/make is GNU
make.
The GNUMakefile has this:
PERL ?= perl
test-t:
$(PERL) Build.PL
If "perl" is not the right thing to use given this context , then what is?
Something is calling "make test" and as best as I can tell that's the
smoker doing it.
If it *is *the case that something in the smoker decided to invoke
"/usr/bin/make test" as it appears above, then how is a makefile supposed
to know which Perl is intended?
Thanks for the help.
