This was installed form the 5.1 iso build from ftp.netbsd.org.  

pkgsrc HEAD

Trying to build p5-Catalyst-Devel:

=> Build dependency xpkgwedge>=1.15: NOT found

ERROR: This package has set PKG_FAIL_REASON:

Stop.

/etc/mk.conf

  X11_TYPE=modular

Where did I go wrong?

Do I need to install pkgsrc xorg? 

TIA,
Paul
