[ensembl-dev] Newbie question: BlastView config for Ubuntu "Lucid" woes

[Nick Langridge]

Hi Bob,

I recently hit the same issue and in the end I reverted to an older 
version of libwww 
(http://backpan.perl.org/authors/id/G/GA/GAAS/libwww-perl-5.814.tar.gz).

Could you install an older vesion to a separate lib dir and use it only 
for Ensembl?

Cheers,
Nick
