I have a hash stored as a Data::Dumper file. When I try to eval this file into my program to rebuild the hash, I am running afoul of the taint checker. "Insecure dependency in eval while running with -T switch at line .... <USRHASH> chunk 1." The string being evaled to recreate the hash can be any length, so I can't do "standard" de-tainting by substr out the individual fields. The Code looks like: 
open(USRHASH,"<$usrhash") or die ......;
flock(USRHASH, LOCK_SH) or die..........;
$/=undef;
eval <USRHASH>;
close (USRHASH);
$/="\n"; 
my %newhash=%$USRLST1; # the reference as created by Data::Dumper

I am hoping someone out there has "laundered" an eval somehow. TIA. gassho "I don't believe in an afterlife, but I am taking a change of underwear." ---Woody Allen
