I had to use a call to asin() in a script. When I tested it at home everything worked perfectly but when it was tried on a remote site the following message appeared: 

Can't locate loadable object for module POSIX \
    in @INC (@INC contains: ... .) 
at /app/foo/master/bin/well_summary_gcrt line 29
BEGIN failed--compilation aborted at \
    /app/foo/master/bin/well_summary_gcrt line 29

Looking at the remote site I found that the POSIX.so file had not been copied. Now I know that I should have copied this file, and I can dispatch a copy of it without any problems. But being a cautious person I want to test this out at home before sending off the file.

I have looked in $PERLLIB, $PERL5LIB and $LD_LIBRARY_PATH and none of them point to a location that contains the POSIX.so file. The path that was compiled into Perl at build time no longer exists, I don't have a /lib/perl or /usr/lib/perl. Yet my script keeps finding the POSIX.so file.

What am I missing? How is Perl managing to locate this file? How can I make my script fail?
