Failure to install icu

[Rem]

/usr/ports/devel/icu is a needed dependency for a program I wish to
install, but icu fails to make. This is the error message I
receive:

SUMMARY:
******* [Total error count:     1]

*** Error code 1

Stop in /usr/ports/devel/icu.
*** Error code 1

Stop in /usr/ports/devel/boost-libs.
*** Error code 1

Can someone please give me a heads up on this one.

Thanks...

Rem
