Using open3 within a Safe reval	Can't Post

I have used Safe->reval to create a new function:

Code

my $method = reval("return sub { $body };");

Within the $body (read from an XML definition) open3 and gensym are used to execute a command. When executing $method:

Code

&{$method}(...)

I get a warning and an exception:

Code

Use of uninitialized value in subroutine entry at (eval 66) line 13. 
Undefined subroutine & called at (eval 66) line 13.

I have tried various ways of "use"ing or "require"ing the necessary packages (even creating a wrapper function I call from within the $body). Nothing seems to work and I always get these errors. I can't seem to catch the first "warning".

Any ideas?
