Not quite.  If you know exactly which perl you want, you specify the exact
path (i.e. #!/usr/bin/perl or #!/cygdrive/c/ActivePerl/bin/perl).  If
you're using just "perl", you get what you paid for (i.e. whatever's in
the path).  I think autoconf uses an explicit path to perl, so $PATH
shouldn't matter much.
Oh, and perl, when installed in /usr/local/bin, usually has a wrapper in
/usr/bin, so using /usr/bin/perl should be pretty portable.
