[Slackbuilds-users] new slpkg-5.4.1 build and runtime errors

[KB_SBo]

Hello Dimitris,

on both my main Slackware64-15.0 multilib and the clean qemu VM 
Sackware64-15.0 (no multilib) I use for Sbo testing, during build of 
slpkg-5.4.1 there is any error:

* Getting build dependencies for wheel...
* Building wheel...

and the package gets built anyway.  This result in the similar syntax 
error but the "bad" line 244 is different.

Traceback (most recent call last):

Seems python isn't too smart when it comes to nested "".  Here the patch:
