Can't build devel/icu even with portmaster -w

[David Demelier]

Hello,

Trying to update, I've read /usr/ports/UPDATING and asked portmaster to
update icu with the -w switch, but I have an error anyway

gmake[1]: Entering directory
`/tmp/ports/usr/ports/devel/icu/work/icu/source/data'

gmake[1]: *** [out/tmp/icudata.lst] Error 1
gmake[1]: Leaving directory
`/tmp/ports/usr/ports/devel/icu/work/icu/source/data'
gmake: *** [all-recursive] Error 2
*** [do-build] Error code 1

my current ICU version is 4.8.1.1 and the ports has THREADS enabled.

Cheers,
David
