Anything you enter on the command line is first interpreted by the  
shell. Using "..." has a special meaning in shells: it means "treat  
everything between these two characters as a single string, but still  
interpret any shell variables or other substitution commands in this  
string". The result is that when fpc asks for the paramstr(x)  
corresponding to this parameter, it will see

-k-install_name libTest.1.dylib

(as one parameter, with the space). Without the quotes, fpc would see  
two parameters, the first one being -k-install_name and the second one  
libTest.1.dylib

If you put parameters inside a configuration file, then those  
parameters are not interpreted by any shell, but read straight away by  
fpc. So if you put -k"-install_name libTest.1.dylib" in there, fpc  
will actually read that exact string. As a result, it will not pass  
this to the linker:

  -install_name libTest.1.dylib

but this:

  "-install_name libTest.1.dylib"

The result is that the linker will not get the two parameters it  
expects (first a parameter called -install_name, followed by a  
parameter with the name of the install name), but one single parameter  
called

  -install_name libTest.1.dylib

There is obviously no linker parameter with that name.

You may want to read some tutorials about unix shell scripting if  
you're going to be working a lot on the command line.
