Hi Ansgar,

Thanks for quick response and for helpful troubleshooting commands.

I was surprised to see "/usr/local" there.
It turned out that I had forgotten symbolic link:

	/usr/local/lib --> /usr/lib

As soon as I removed it the above command returned expected

	/usr/lib/perl5/Compress/Raw/Zlib.pm

and everything returned back to normal.
I guess the question is why libio-compress-perl is sensitive to contents of /usr/local ?
Perhaps it is a bit unexpected...

With symlink (/usr/local/lib --> /usr/lib):

	Compress::Raw::Zlib version 2.052 required--this is only version 2.033 at /usr/share/perl5/Compress/Zlib.pm line 11.
	BEGIN failed--compilation aborted at /usr/share/perl5/Compress/Zlib.pm line 11.
	Compilation failed in require.
	BEGIN failed--compilation aborted.

After removing symlink (/usr/local/lib --> /usr/lib):

	/usr/share/perl5/Compress/Zlib.pm
