My module + external framework = running only on my own mac??

Dear community,

I have big problems with my module. The thing is I embed in my module.xconfig an external Framework like this:

OTHER_LDFLAGS[sdk=iphoneos*]=$(inherited) -F$(SRCROOT)/../../modules/iphone/my.module/1.0/platform/iphone -F"$(TI_SDK_DIR)/../../../../modules/iphone/my.module/1.0/platform/iphone" -framework ExternalFramework
 
OTHER_LDFLAGS[sdk=iphonesimulator*]=$(inherited) -F$(SRCROOT)/../../modules/iphone/my.module/1.0/platform/iphone -F"$(TI_SDK_DIR)/../../../../modules/iphone/my.module/1.0/platform/iphone" -framework ExternalFramework

Now when I compile it on my mac, everything works fine. But when I try to compile it on an other mac with "titanium run", I get this error:

[ERROR] :  ** BUILD FAILED **
[ERROR] :  The following build commands failed:
[ERROR] :  Ld build/Debug-iphonesimulator/mymodule.app/mymodule normal i386
[ERROR] :  (1 failure)

How can I solve this problem? I already tried everything I was able to?!

Kind regards, Alex
