fetch.ignore_sslcert yes still checking ssl cert

[Adam Mercer]

Hi

The upstream sources of a few packages I maintain have recently
switched to be served over https. Fetching from this https server is
failing with the following:

Warning: couldn't fetch
https://www.lsc-group.phys.uwm.edu/daswg/projects/metaio/release-7-2/metaio-7.2.tar.gz
for metaio (peer certificate cannot be authenticated with known CA
certificates)

After consulting the guide I added:

fetch.ignore_sslcert yes

to the Portfile, yet the fetch still fails with the above. Isn't the
fetch.ignore_sslcert statement supposed to supress this?

Cheers

Adam
