Building jdk-1.8 stuck

[nyg]

Hello,

I'm trying to compile the jdk-1.8 with the with_ipv6 flavor but it's stuck here:

===> py-crypto-2.6.1p2 depends on: python->=2.7,<2.8 -> python-2.7.12
===> py-crypto-2.6.1p2 depends on: gmp-* - not found
===>  Verifying install for gmp-* in devel/gmp
===>  Checking files for gmp-5.0.2p3
>> Fetch ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2

OpenBSD is running inside VirtualBox so I'm thinking there's kind of network issue. Strange thing is that:

curl ftp://ftp.cc.uoc.gr/mirrors/OpenBSD/ftplist

works, but

curl ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2 -o output

doesn't. It does on the host OS however.

How can I debug this?

EDIT:

# curl -v ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2 -o output
