srfi-18 chicken install error

[Nick]

As I was attempting to install Chicken Egg 'sql-de-lite', on my Windows 10 
system (Chicken 5.2.0), I got the following error.

It appears to me that the srfi-18 build script 'srfi-18.build.bat' is 
constructed incorrectly, in that, the command clause of the constructed 
'chicken-do' command is attempting to execute the batch file

C:\Users\nick\AppData\Local\chicken-install\srfi-18\build-srfi-18.bat

when, instead, it should attempt to execute the chicken compiler command, 
namely:

c:/chicken_compiled/bin/csc

I get the same error if I attempt to install 'sfri-18' separately.

I'm not familiar enough with Chicken, or the Chicken Egg extensions, to 
understand why this is happening. Although, from what I understand, from 
reading the Chicken documentation, the .egg file is supposed to provide 
configuration information that is used to construct the build batch scripts. Is 
there an issue with the .egg file?

I have attached the file 'srfi-18.build.bat.txt' ('srfi-18-build.bat' generated 
from the command 'chicken-install srfi-18') for further reference.
