When compiling bulk build environment under Ubuntu 10.04 GNU/Linux (cd 
pkgtools/pbulk; bmake install), I get this error:

gcc -Wno-error -Wno-error  -Wall -Wstrict-prototypes -Wmissing-prototypes 
-Wpointer-arith -Wno-uninitialized -Wreturn-type -Wcast-qual -Wpointer-arith 
-Wwrite-strings -Wswitch -Wshadow -Werror  -D_GNU_SOURCE -DHAVE_NBCOMPAT_H=1 
-I/usr/pkgsrc/pkgtools/pbulk-base/work/libnbcompat -c read_child.c
cc1: warnings being treated as errors
read_child.c: In function 'read_from_child':
read_child.c:73: error: format not a string literal and no format arguments
*** Error code 1

This is related to more strict checks newer versions of gcc do...
Under Ubuntu 10.04 GNU/Linux, with GCC 4.4.3 , after bootstrapping pkgsrc:

    # cd /usr/pkgsrc/pkgtools/pbulk
    # bmake install
Apply this patch against pkgtools/pbulk/files/pbulk/lib/read_child.c
