>Description:
The change from

Module Name:    pkgsrc
Date:           Sun Apr 17 23:04:56 UTC 2016

Modified Files:
        pkgsrc/graphics/MesaLib: Makefile

Log Message:
According to a Linux bulk build, this needs a lex. Add it to tools.

probably should have been to add flex as a tool in the Makefile, not lex.

make clean && make configure

checking if bison is the parser generator... yes
checking for flex... /usr/bin/lex
checking lex output file root... lex.yy
checking lex library... -lfl
checking whether yytext is a pointer... yes
checking if flex is the lexer generator... no
configure: error: flex not found - unable to compile glcpp-lex.l
*** Error code 1


>How-To-Repeat:
The NetBSD system on which the above error occurs has in /etc/mk.conf:

PREFER_PKGSRC= yes

CFLAGS+= -g
INSTALL_UNSTRIPPED=yes
USE_DESTDIR=yes
X11_TYPE=modular
ACCEPTABLE_LICENSES += vim-license lame-license vera-ttf-license
ALLOW_VULNERABLE_PACKAGES=yes

CURSES_DEFAULT=ncurses
READLINE_DEFAULT=readline

The error has also been observed on a DragonFly 4.5-DEVELOPMENT system.
>Fix:
The fix below allows make configure to complete successfully but has not been tested to see if the full package builds and replaces.
