The examples at the end of g_select -select 'help all' pretty well cover most of 
these situations.  What have you tried?  What has it given you?  Something like:

same residue as resname SOL and within 0.5 of residue X

provided that residue X is defined within an .ndx file provided on the command, 
line should work.  Disclaimer: this is just off the cuff, but probably pretty close.
