pkgsrc circular dependancy

[Raymond Meyer <raymond.meyer%rambler.ru@localhost>]

ÂHi, I'm trying to use pkgsrc-current on solaris 10. I built and 
installed pkgsrc bootstrap utilities and noticed that things like tar 
and ftp were not built... Anyway, trying to build a package results in 
the following:

pkgsrc tries to build net/tnftp
this needs ncurses
ncurses need net/tnftp
... and pkgsrc locks up here

Any comments/ideas??
