scala - Missing sbt/boot/ directory in new play-2.1.1 installation. Playframework installation on Linux Mint 14 -

i'm trying install play! framework on linux mint box, i'm having hard time getting play going. after installation, i'm getting folliwing error message when type play @ command line:

    $ play java.io.filenotfoundexception: /home/play-2.1.1/framework/sbt/boot/update.log (no such file or directory)     @ java.io.fileoutputstream.open(native method)     @ java.io.fileoutputstream.<init>(fileoutputstream.java:218)     @ java.io.fileoutputstream.<init>(fileoutputstream.java:171)     @ java.io.filewriter.<init>(filewriter.java:90)     @ xsbt.boot.update.<init>(checks.java:51)     @ xsbt.boot.launch.update(launch.scala:275)     @ xsbt.boot.launch$$anonfun$jnaloader$1.apply(launch.scala:120)     @ scala.option.getorelse(option.scala:108)     @ xsbt.boot.launch.jnaloader$2f324eef(launch.scala:115)     @ xsbt.boot.launch.<init>(launch.scala:94)     @ xsbt.boot.launcher$.apply(launch.scala:290)     @ xsbt.boot.launch$.apply(launch.scala:16)     @ xsbt.boot.boot$.runimpl(boot.scala:31)     @ xsbt.boot.boot$.main(boot.scala:20)     @ xsbt.boot.boot.main(boot.scala) error during sbt execution: java.io.filenotfoundexception: /home/play-2.1.1/framework/sbt/boot/update.log (no such file or directory) 

as can seen, play installed in /home directory. content of .bashrc file follows:

$ cat ~/.bashrc export path=""/home/play-2.1.1:$path"" export java_home=/usr/local/java/jdk1.7.0_12 export path=$java_home/bin:$path export classpath=$java_home/lib/dt.jar:.:$java_home/lib/tools.jar:$java_home/jre/lib/rt.jar 

i wonder if i've left out during installation process accounts difficulty in getting play , running. appreciate helpfull hints , advise. many thanks.

make sure have write permissions on play framework path. error if not.
