Struggling to get import-spweb to succeed

I performed an export-spweb on a site. I copied the folder containing the export to my test machine. 

I then performed

Import-spweb –identity http://myfarm/sites/dest/d62 -Path d:\temp\d22 –verbose –force –nofilecompression -includeusersecurity  -includeversions all

I got the following as a result:

VERBOSE: Leaving BeginProcessing Method of Import-spweb.
VERBOSE: Performing operation "Import-SPWeb" on Target "Import the contents in package d:\temp\d22 to the
destination site specified by http://myfarm/sites/dest/d62. By default, all files will be imported
as new versions of any existing file.".

Log file generated:
        d:\temp\d22\import.log

Import-SPWeb : Could not find file 'C:\Users\sa_spsdev\AppData\Local\Temp\2\us4vkzep.dll'.

I don't have any idea what is going on.

A week ago, I exported the same site, imported it to this location, encountered a problem with some of the data in the export files, and had the owners remove the broken libraries.

At this point, I expected the import to work. Instead, it failed without a useful error. If the import expected to find something in that path, it would be something that the import put there. So why would it not be found?
