Subject: work around CGI::Session constructor issues
X-Git-Url: https://scripts.mit.edu/gitweb/www/ikiwiki.git/commitdiff_plain/5d26ded3811cd050a1c70ccf76f3022a787a9588

work around CGI::Session constructor issues

The constructor can fail with a useless error message if module fail to
load. Work around this by evaling it, and checking for failures, and
printing CGI::Session->errstr to get a more useful message.
