How to install PostgreSQL 9.3 in FreeBSD jail?

I configured virtual NICS using pf, and a jail for FreeBSD using qjail create pgsql-jail 192.168.0.3. When I tried to install PostgreSQL 9.3 using port collection, it shows strange message at first. pgsql-jail /usr/ports/databases/postgresql93-server >make install ===> Building/installing dialog4ports as it is required for the config dialog ===> Cleaning for dialog4ports-0.1.5_1 ===> Skipping 'config' as NO_DIALOG is defined ====> You must select one and only one option from the KRB5 single *** [check-config] Error code 1 Stop in /basejail/usr/ports/ports-mgmt/dialog4ports. *** [install] Error code 1 Stop in /basejail/usr/ports/ports-mgmt/dialog4ports. ===> Options unchanged => postgresql-9.3.0.tar.bz2 doesn't seem to exist in /var/ports/distfiles/postgresql. => Attempting to fetch ftp://ftp.se.postgresql.org/pub/databases/relational/postgresql/source/v9.3.0/postgresql-9.3.0.tar.bz2 postgresql-9.3.0.tar.bz2 1% of 16 MB 71 kBps Anyway, installation continues, so I waited. I chose all default options for all option dialogs. And at the end of the process, I saw it finally failed with this message. ====> Compressing man pages ===> Building package for pkgconf-0.9.3 Creating package /basejail/usr/ports/devel/pkgconf/pkgconf-0.9.3.tbz Registering depends:. Registering conflicts: pkg-config-*. Creating bzip'd tar ball in '/basejail/usr/ports/devel/pkgconf/pkgconf-0.9.3.tbz' tar: Failed to open '/basejail/usr/ports/devel/pkgconf/pkgconf-0.9.3.tbz' pkg_create: make_dist: tar command failed with code 256 *** [do-package] Error code 1 Stop in /basejail/usr/ports/devel/pkgconf. *** [build-depends] Error code 1 Stop in /basejail/usr/ports/textproc/libxml2. *** [install] Error code 1 Stop in /basejail/usr/ports/textproc/libxml2. *** [lib-depends] Error code 1 Stop in /basejail/usr/ports/databases/postgresql93-server. *** [install] Error code 1 Stop in /basejail/usr/ports/databases/postgresql93-server. I have no idea why this fails. Errors at beginning seems I have something wrong with dialog4ports. And errors at last seems installer cannot write to ports file tree. AFAIK, the ports files are read-only shared from host system. What's wrong with my jail? How can install PostgreSQL 9.3 in my jail?
