That is rather odd; the first thing it occurs to me to check is whether on the affected system some environment variable such as PERL5LIB or PERLLIB PERL5OPT could be introducing a use integer or use bigint, or even to check the contents of %INC to see if anything like that is getting loaded.

I've never heard of a system on which a perl build simply truncated decimals of its own accord - such a build certainly wouldn't pass much of the test suite.

Update: corrected the name of the environment variable.
