Thunderbird 2.0 compile problem with FreeBSD

[me at alexdyas.com]

Hello,

It seems there is a missing dependency check for the Thunderbird 2.0 
port under FreeBSD.  I got the following error:

<snip>

nsSmtpProtocol::AppendHelloArgument(nsACString_internal&)':

which was fixed when I upgraded the nspr-4.6.1 package to nspr-4.6.6.
