Android : Configure proguard.sh with proguard and Mac OS

Im trying to export android apk with proguard, however this error occured :

   Users/thanhnguyen/Documents/mr thao's music/android-sdk-macosx/tools/proguard/bin/proguard.sh: line 10: "/Users/thanhnguyen/Documents/mr thao's music/android-sdk-macosx/tools/proguard": No such file or directory 
   Unable to access jarfile /Users/thanhnguyen/Documents/mr
   at com.android.ide.eclipse.adt.internal.build.BuildHelper.runProguard(BuildHelper.java:623)
   at  com.android.ide.eclipse.adt.internal.project.ExportHelper.exportReleaseApk(ExportHelper.java:259)
... 4 more

It seems that I must configure file proguard.sh, the default is :

 PROGUARD_HOME=`dirname "$0"`/..

 java -jar $PROGUARD_HOME/lib/proguard.jar "$@"

My proguard.jar is at : /Users/thanhnguyen/Documents/mr thao's music/android-sdk-macosx/tools/proguard on Mac OS.

I tried to set but didn't work :

 PROGUARD_HOME="\"/Users/thanhnguyen/Documents/mr thao's music/android-sdk-macosx/tools/proguard\""

 java -jar "$PROGUARD_HOME/lib/proguard.jar" "$@"

How could I change proguard.sh, if not change, what could be the rearson for proguard error?

Thanks a lot!
