#5 readline.h check during ./configure

[Pascal V.]

Dear mutella mates,

I am trying to install mutella on a computer which runs
NetBSD 1.6.2_STABLE

$ ./configure --prefix=$HOME --exec-prefix=$HOME

teminates with this error:

checking readline/readline.h usability... yes
checking readline/readline.h presence... yes
checking for readline/readline.h... yes
checking for readline in readline.h... no
checking for readline in readline.h with curses... no
checking for readline in readline.h with ncurses... no
checking for readline in readline.h with termcap... no
configure: error: You must have readline library!

I tried ./configure --prefix=$HOME --exec-prefix=$HOME
--with-readline=/usr/include

and /sys/pkg/include/ where another readline.h is
installed (I don't know why?)
but still get the same final error

Has somebody already seen and solved this?

Thanks if yes

Pascal
