Trouble building packages Fedora 13

Hi I having problems building the packages under fedora 13. [m-jackson@Oz build]$ ant Buildfile: build.xml

build:

revision-check:

linux-checkos:

subprojects-build:

compile:

BUILD FAILED /home/m-jackson/Arduino/build/build.xml:28: The following error occurred while executing this line: /home/m-jackson/Arduino/build/build.xml:60: The following error occurred while executing this line: /home/m-jackson/Arduino/core/build.xml:13: java.lang.NoSuchMethodError: method java.util.regex.Pattern.quote with signature (Ljava.lang.String;)Ljava.lang.String; was not found.

I believe I have the deps needed but I don't see what is causing these errors. Would someone kindly give me a hint. I issued the ant command within the build directory as a normal user. Thanks
