Well, let's see now...
#!/usr/bin/perl sub p{($p::P)=@_;for$P(2..sqrt($p::P)){$P::p=$p::P/$P;($P::p==int($P:: +p)) && return(0);}return($p::P>1)};$p::p=3;$\=$,=$/;$P::P=0; p:for$p(1..($p::p-1)){p($P=$p**2+$p+$p::p)&& push(@P,$P)} for$p(1..$#P){$P[$p]=(grep{($_!=$p)&&($P[$_]==$P[$p])} (0..$#P))?0:$P[$p]}$p::p=0;$p::p=$P[$P::P++]until$p::p; $P[@P]=@P;$_||($P[-1]--)for@P;(pop(@P)>=$ARGV[0])||goto p; print((sort{$a<=>$b}grep{$_}(2,@P))[0..$ARGV[0]-1]);

Update: Thanks to jynx for pointing out the duplicates printed by the original version. Should be fixed now, and perhaps slightly more obfuscated as well.

[RonW]: james28909 Why not write a Perl program to do the task?
[choroba]: RonW Yes, but then, one day, they needed to switch from FTP to SFTP, and... but I can't give the whole talk away here :)
[RonW]: Tunnel FTP through stunnel?
[james28909]: i guess i should have done it in perl. i bet it woulnt have taken me 5 hours to figure out haha
[choroba]: In the end, I was able to upgrade Perl from 5.8.3 to 5.22 and install Net::SFTP::Foreign , at least for the task involved
