Looks like, perldoc pager adds the temporary file as last argument, but
you told Vim to read the file from standard input.

You should make a script out of it, e.g. something like this:
#!/bin/sh

col -b -x <$1|vim -R -c 'set ft=man' -

Or try to use this one liner (not sure, this works everywhere):

export PERLDOC_PAGER="sh -c \"col -b -x| vim -R -c 'set ft=man' - \" <"
