G'day wwinfrey,

"The same DSN works if I provide filesystem paths."

Although you're naming those variables as $xxx_file_location, they're not locations at all: they're filehandles which will stringify to something like GLOB(0xffffffffffff): 

$ perl -wE 'my $x; open my $f, "<", \$x; say $f'
GLOB(0x7fb509805480)

As a basic debugging technique, print questionable strings before using them. In this case, I imagine $dsn contains parts that look like: 

...mysql_ssl=1;mysql_ssl_ca_file=GLOB(0xffffffffffff);...

Purely as a suggestion, because I have no way of testing this, you could look at the core module File::Temp.
