System: Linux idran 2.6.30 #2 PREEMPT Sun Aug 9 18:32:44 NZST 2009 i686 
pentium4 i386 GNU/Linux
Architecture: pentium4
Machine: i686
C library: GNU C Library stable release version 2.10.1
C compiler: cc (GCC) 4.4.1

To compile netpgp under glibc the following glibc feature test macros need to
be defined:

_XOPEN_SOURCE for strptime(3)
_BSD_SOURCE for strdup(3) and strcasecmp(3)

cd security/netpgp ; bmake

libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I../../include 
-I/tmp/pkgsrc/security/netpgp/work.idran/.buildlink/include -Werror -Wall 
-Wpointer-arith -O2 -pipe -march=i586 -mtune=generic -MT libnetpgp_la-netpgp.lo 
-MD -MP -MF .deps/libnetpgp_la-netpgp.Tpo -c netpgp.c  -fPIC -DPIC -o
