Missing libs in Mac bundle

[shawnlaffan]

Mac users have reported being unable to open files when importing data.

The logs indicate that the via layer cannot be found.

Unknown PerlIO layer "via" at Biodiverse/GUI/BasedataImport.pm line 384.

A comparison of the packed Mac version with the Windows one indicates the following are missing:

PerlIO::encoding
PerlIO::via
encoding.pm
File::HomeDir
File::Which
Math::BigFloat::
Math::BigInt::

The File:: and Math:: libs might not be essential, though.

A possible cause is that the PAR::Packer version used to pack the Mac version is slightly older.

This gets it to work. We probably only need to specify -M PerlIO::, though.

perl bin/mmb3.pl -s ../../bin/BiodiverseGUI.pl -o . -x -- -M PerlIO:: -M encoding -M File::Which -M File::HomeDir

The workaround for users is to convert their CSV files to spreadsheet formats (e.g. MS Excel or OpenOffice Calc) and import them directly.

Marking as fixed.
