Well, bypassing perl (why reinvent the wheel?) I'd do this:
find /the/dir -type f -print | sort | comm -23 - /the/list/to/exclude
Where /the/dir is the directory you're recursing through and
/the/list/to/exclude is the file containing the filename you don't
want. It must be sorted (comm needs both inputs to be sorted).
Simple and effective.
