What makes you think so? From the log you posted:
| Registering extension prefix str : http://exslt.org/Strings
| LIBXSLT_PLUGINS_PATH is (null)
| Attempting to load plugin:
| /home/ensonic/lib/libxslt/1.1/exslt_org_Strings.so for
| URIhttp://exslt.org/Strin
| xmlCheckFilename failed for plugin:
| /home/ensonic/lib/libxslt/1.1/exs_org_Strings.so
| xsltPrecomputeStylesheet: removing ignorable blank node ltgs: 


Doesn't look like a successful load to me. Does the library exist
at 'home/ensonic/lib/libxslt/1.1/exs_org_Strings.so'?

Dynamic loading attempts to load the library every time it the function
gets called. And fails ...
