Hello fellow Guixers,

So ledger fails to install with the following

#+BEGIN_EXAMPLE
99% tests passed, 5 tests failed out of 352

Total Test time (real) =  37.60 sec

The following tests FAILED:
         47 - BaselineTest_dir-import_py (Failed)
         49 - BaselineTest_dir-python_py (Failed)
         59 - BaselineTest_feat-import_py (Failed)
        104 - BaselineTest_opt-datetime-format (Failed)

What can one do to fix this error and get it working again?

Suppose we could install an older version of ledger if there is an older version
in the substitutes (correct word?) if it exists.
