That is correct. However Stephen has put his customized balsheet-fmtd.scm 
report in
/usr/local/share/gnucash/scm/gnucash/report
instead of
/usr/local/share/gnucash/scm/gnucash/report/standard-reports

Files in the former directory are not automatically loaded, a historical 
artifact we should one day fix.

What is different about the e-guile reports is that they are business reports. 
And contrary to the standard reports they are only loaded if explicitly 
mentioned in
/usr/local/share/gnucash/scm/gnucash/report/business-reports.scm
(in a use-modules construct).

This is the problem IMO. The attached balsheet-fmtd.scm (renamed to balsheet-
eg.scm) defines this module:
(define-module (gnucash report balsheet-fmtd))
As this file replaces balsheet-eg.scm there no longer is a module defined by
(define-module (gnucash report balsheet-eg))

And hence gnucash complains it can't find that one.

To solve this, restore the original balsheet-eg.scm and instead add a line in 
business-reports.scm like this:

(use-modules (gnucash report balsheet-fmtd))

Better still: don't mess with the installation directory at all and instead 
follow
https://wiki.gnucash.org/wiki/Custom_Reports#Loading_Your_Report
to load your custom report.
