>Description:
pkgsrc seems to corrupt ${PATH} for paths that have space in them. This maket impossible to run executables from those folders.
>How-To-Repeat:
Add to your normal PATH (say in ~/.profile) some folder that has space in it:

PATH=$PATH:/Demo\ Folder/bin

Note how pkgsrc is unable to execute anything from that bin/ folder.

Echoing ${PATH} from the pkgsrc Makefile shows that the path space has been replaced by ':' so it was split in two paths.

/Demo:Folder/bin


>Fix:
Avoid folders with space in them.
