Strange stap error...

[Steve Dickson]

I'm getting the following error:

$ sudo ~/bin/stap -g inode_permission.stp 
gpg: no default secret key: No secret key
gpg: signing failed: No secret key
Copy failed ("/tmp/stapwUrw9k/stap_f69367bbfe0f310d5472acdca1010f45_2000.ko" to "/home/steved/.systemtap/cache/f6/stap_f69367bbfe0f310d5472acdca1010f45_2000.ko"): No such file or directory

Using the following version of stap (straight out of the git tree)
 
$ ~/bin/stap -V

Using a relativity new kernel...

$ uname -a
Linux redhat 2.6.32-2.nfs41.el6.x86_64.debug #1 SMP Fri Dec 18 08:42:45 EST 2009 x86_64 GNU/Linux


With the following tap script

$ cat inode_permission.stp 
probe kernel.function("inode_permission")
{
	printf("inode_permission: inode %p mask 0x%x\n", $inode, $mask);
}
probe kernel.function("inode_permission").return
{
	printf("  inode_permission: return %d\n", $return);
}

probe begin { log("inode_permission probe") }
probe end { log("inode_permission probe") }


any ideas?
