The issue seems to be that powl() is not implemented on freebsd yet and just fallbacks to the imprecise pow(). Some pointers:

The problem is that this equation does not hold here:
$ perl5.20.1D -MMath::Trig -MTest::More=no_plan -e 'is((sinh(1)+cosh(1))**1, sinh(1)+cosh(1))'
not ok 1
# Failed test at -e line 1.
# got: '2.71828182845904509'
# expected: '2.71828182845904524'
1..1
# Looks like you failed 1 test of 1.
Easiest solution: add "**1" to the expression in the failing test. This should not change anything on other systems, and helps in this situation. See the attached patch.

Subject: [PATCH] workaround for RT #112530
The exp(1) in t/06virtual.t used to fail on system with imprecise pow
(e.g. on freebsd systems with perl compiled with -Duselongdouble). Fix
this issue by adding a "**1" to the expected value.
