__fpclassifyd problem

Hello

I'm trying to install java-checkstyle on my 5.1 system, the system is 
upto date (p10) but I get this build error:

===[root] /usr/ports/java/java-checkstyle # make
===>  Extracting for java-checkstyle-3.1
 >> Checksum OK for checkstyle-src-3.1.tar.gz.
===>  Patching for java-checkstyle-3.1
===>   java-checkstyle-3.1 depends on file: /usr/local/bin/ant - found
===>   java-checkstyle-3.1 depends on file: 
/usr/local/diablo-jdk1.3.1/bin/java - found
===>  Configuring for java-checkstyle-3.1
===>  Building for java-checkstyle-3.1
/usr/libexec/ld-elf.so.1: /usr/lib/libm.so.2: Undefined symbol 
"__fpclassifyd"
*** Error code 1

Stop in /usr/ports/java/java-checkstyle.


What I understand is that the problem is that I can have some stale libs 
in /usr/lib
how can I solve this?
